Knowledge, skills and attributes
Astronomers help people understand the mysteries of the universe. They come
up with theories of how stars are born and how the universe evolves, and
they conduct research to collect data for analysis. They use telescopes and
scientific instruments to study planetary phenomena and measure light, radio
and X-ray emissions from space. There’s plenty of work with the public, too.
Some astronomers run planetariums, putting together public presentations or
discussing findings at science conferences. Raising money for research is
part of the job as well.
Astronomers need specific skills for the job. Because the field blends
physics and chemistry, astronomers need to know how to use scientific
methods, such as observation and measurement, to answer research questions.
To solve problems, astronomers need thinking skills, including logic, reason
and judgment. Computer skills help them analyze large data sets or make
complex calculations. Also, communications skills are invaluable.
Astronomers write papers, reports and lecture notes that are technical, but
easy to understand for students, the public and other astronomers.
Public-speaking skills enable astronomers to present findings to peers.

need to obtain proper security clearance.
Did You Know? (Source: ingimage - purchased) On July 21st 1969, the world gathered around TV sets and collectively held their breath as Neil Armstrong declared his famous words, "That's one small step for man. One giant leap for mankind," and set foot on the lunar surface for the first time. It's a moment in history that's etched in the memories of people who saw it. It has since transcended the decades to still be a defining moment in the world's modern history. On that cold, squally day in central west NSW, the Parkes Radio Telescope, 'the Dish', played an integral role in getting the television pictures of man first walking on the moon to the world. To cover the landing, NASA was set to use a telescope at Goldstone in California as the main receiver, with Parkes and Honeysuckle Creek near Canberra set to be backups. The Parkes Telescope was chosen due to its size (being 64m in diameter, it had seven times the sensitivity for collecting signals). "NASA wanted to have three stations equally spaced, so as the Earth rotated, they could have continuous coverage," says John Sarkissian, an Operations Scientist for the CSIRO based at the Dish. "The Parkes Radio Telescope was recognised as a world leader in radio astronomy. Within the [astronomy] community, everybody knew that they were the go-to country." On the day, the Dish had to overcome a number of significant hurdles in order to play the critical role that it did. "The conditions at the time here were terrible," says John. "Just moments before the moonwalk began a violent wind squall hit the telescope. The Dish was fully tipped-over at its most vulnerable when it was hit by two gusts exceeding 110km/h, and that actually made the telescope slam back against its zenith axis pinions causing the tower to shudder and sway. "John Bolton, the Director of the observatory at the time, ordered his men to stay on the Dish, and just as Buzz Aldrin switched on the TV cameras, the winds abated and they received the signals. "The astronauts may very well have been on the Sea of Tranquillity on the moon, but it was most definitely the ocean of storms here at Parkes at the time."  (Source: National Portrait Gallery) For the first eight minutes of the broadcast NASA switched between the pictures that were being received by Parkes, Honeysuckle Creek and Goldstone, before finally settling on using Parkes' signal for the rest of the two-and-a-half hour moonwalk. The other significant challenge faced by the Parkes team involved the timing of the moon rise above NSW and the start of the moonwalk. Due to a change in the mission schedule, the moonwalk was to begin later than originally planned at 4.20pm AEST, meaning Parkes was to become the primary receiving station as the moon would've set in the USA. But Neil Armstrong decided to begin the moonwalk earlier, meaning the moon hadn't yet risen above Parkes. Just before 1pm the Parkes scientists thought of a solution to still be able to cover the landing. "John Bolton realised that if they positioned the [second, weaker] receiver just right, they could actually pick up the signal," says John. "Just as Buzz Aldrin switched on the TV camera, they were able to pick up the signal. "What started off with Parkes perhaps not getting any pictures, ended up with them getting the entire picture and the majority that the world saw. And all this happened during a wind squall." John says he's proud to work at the Dish and be surrounded by its rich history. "It was a great moment in the history of the Parkes Telescope. We allowed the world to witness that remarkable event with the greatest possible clarity, and at the time, the rest of the world had no idea what the conditions were like here. "When Armstrong said, 'It's a giant leap for mankind,' he meant it, and the world understood it as that," he says. "It really is something that Australians should be proud of."

Did You Know? Dr Brett Addison CAMEO 27 April 2021 Australian astrophysicist, Dr Brett Addison, helps discover a new PLANET 490 light years away - but there are a few problems if humans plan to live on it An Australian astrophysicist has helped discover a new planet, TOI-1431b It is 490 light years away and would vaporise any metal on the human body The planet's daytime temperature is 2700C making it impossible to live there (Source: Daily Mail UK) Local Copy  Dr Brett Addison TOI-1431b was first spotted by NASA's Transiting Exoplanet Survey Satellite (TESS), but at that stage no one knew it was a planet. Dr Addison and his team had to do months of careful data analysis to prove that what was initially called a 'TESS object of interest' was indeed a planet. 'I could slowly start to see an orbit ... forming in the data, and as we collected more and more data I could see 'OK this is definitely a planet',' he said. 'It's so hot that absolutely nothing could survive. But it's still really interesting because we can study the atmosphere of these planets and understand how planets form and migrate.' TOI-1431b was not always were it is now, and did not form close to the star that now acts as its host. Over time it has migrated into the very tight orbit that creates its 'hellish' climate. Not content with standing out for its roaring temperature, the newly discovered planet is also orbiting backwards around its searing star. 'If you look at the solar system, all the planets orbit in the same direction that the sun rotates, and they're all along the same plane,' Dr Addison says. 'This new planet's orbit is tilted so much that it is actually going in the opposite direction to the rotation of its host star.' Brett is an Adjunct Research Fellow at the University of Southern Queensland (UniSQ) in the Centre for Astrophysics. He is working with Prof. Rob Wittenmyer and his international team of collaborators on discovering and characterising new exoplanets using the MINERVA-Australis telescope array facility at the Mt. Kent Observatory in Queensland, Australia. He worked on his PhD at the University of New South Wales, titled “Measuring the Spin-Orbit Alignments of Extrasolar Planets”, which was conferred in April 2015. After completing his PhD, he moved to Mississippi State University in December 2015 for his first postdoctoral research position, before moving to UniSQ and joining the MINERVA-Australis team in August 2018. Brett’s research work involves the detection and characterisation of exoplanets. He is using MINERVA-Australis to carry out radial velocity follow-up observations of transiting planet candidates orbiting bright nearby stars found by the Transiting Exoplanet Survey Satellite (TESS) that are observable from Mt. Kent. These observations are confirming new TESS planets as well as measuring their bulk properties such as mass, density, and orbital eccentricity. The aim of his research is to understand the diversity of exoplanets in our galaxy, their formation and migration processes, and the search for life on other planets.

Duties and Tasks
Because most astrophysicists work for either government agencies or universities, their responsibilities are often much broader than just collecting data and doing research. A long-term position as an astrophysicist can include teaching, overseeing Ph.D. candidates, writing grant proposals, reviewing the research of other scientists, giving speeches, attending conferences, managing a department and scheduling time at one of the powerful telescopes that astrophysicists depend on for their research. Despite all of these additional responsibilities and demands on their time, most astrophysicists still have a lot of leeway to conduct their own independent research.
Working conditions
The workplace of an astrophysicist can vary
depending on factors such as the nature of their research, the
institution they are affiliated with, and the specific projects they are
involved in. Astrophysicists can be found working in a range of
settings, including universities, research institutions, government
agencies, and observatories.
Many astrophysicists are employed by universities and research
institutions where they conduct research, teach courses, and supervise
graduate students. These academic settings provide access to
observatories, laboratories, and computational resources necessary for
their work. Astrophysicists often collaborate with colleagues on
research projects, contribute to the academic community through
publications, and engage in educational activities.
Tools and technologies
Astrophysicists use complex optical or radio telescopes to observe the universe and answer the fundamental questions of physics, such as how stars and galaxies are formed.
Education and training/entrance requirements
Astrophysicists require extensive education and training. You need to earn a bachelor's degree in science. To work as an astrophysicist, the first step is to complete an undergraduate degree in physics with an honours year, followed by a Ph.D. You then need to pursue a research career. These are normally jobs that last two to four years and you may take on a few of them in different countries before securing a permanent post.
Employment Opportunities
There are various opportunities for Astrophysicists in Australia with the CSIRO Australian Telescope National Facility being one of them. Others include:

Cosmology is a branch of science which studies
the evolution of our universe. A scientist who studies cosmology is
called a cosmologist. Cosmologists want to know what the universe was
like billions of years ago. They want to understand how it is today.
They also want to find out what the universe will be like billions of
years in the future.
To understand the universe, cosmologists first needed to know our place
in it. About 400 years ago, most people believed that Earth was at the
center of the universe. They thought the Moon, the Sun, and the other
planets all traveled around Earth. Nicholas Copernicus, Galileo Galilei,
and Isaac Newton helped us to learn the truth. We now know that the Moon
travels around Earth. Earth and the other planets in our solar system
travel around the Sun.
About 100 years ago, astronomer Edwin Hubble made observations that
showed the universe was getting bigger and bigger! This led most
cosmologists to believe in a theory called the Big Bang. The Big Bang
theory says the universe began with a huge explosion ten to twenty
billion years ago. Cosmologists think the universe did not exist before
the Big Bang. Some cosmologists think the universe will keep getting
bigger forever. Other cosmologists think the Universe will someday start
getting smaller. They think it will shrink until it no longer exists. No
one knows yet which opinion is correct.

Did You Know? Difference between a cosmologist and an astronomer The primary difference between a cosmologist and an astronomer is their research. Both cosmologists and astronomers are interested in understanding and testing theories about the way the universe works. Although they can often share work environments and collaborate on projects, their research and job duties differ. Cosmologists study theories about the creation and development of the universe. This includes theories about the history of the universe, like the Big Bang theory and particle physics. Astronomers, conversely, are primarily interested in celestial bodies, meaning things that exist in space. This includes planets, stars and galaxies. (Source: Indeed) |
Working conditions
Cosmologists study, examine and work out
theories including string theory, dark energy, dark matter, multiverses
and and how many dimensions there may be in our universe. Although it is
possible that you may spend some of your time looking through a
telescope, this isn't very common for a cosmologist. Instead, they work
with data collected by others, usually on computers, analyzing it, while
exploring and testing theories.
Depending on the work you do, and which area of cosmology you specialize
in, it is possible you may be working with large and expensive
equipment, like particle accelerators or nuclear reactors. However, even
then, most of the work is done in an office on a computer.
Cosmologists typically work in academic institutions, research centers, or observatories. They may also work for governmental agencies or private organizations involved in space exploration and astronomy. The work environment often involves a combination of theoretical work, computer modeling, and data analysis. Cosmologists may work irregular hours, especially during observation campaigns and research deadlines. They may also have opportunities to collaborate with international research teams and participate in conferences worldwide.
Tools and technologies
A cosmologist is a scientist who uses space-based and ground-based telescopes and satellites to study the properties of the universe, including planets, black holes and galaxies. They obtain data and observe certain aspects of astronomical objects, including distance, size, motion and brightness. Cosmologists use their data to test and create theories, such as string theory and theories of dark matter, regarding various phenomena. Their work can lead to practical and scientific advancements in electronics, energy, navigation and medical technology.
Education and training/entrance requirements
1. Pursue a bachelor's degree
If you're interested in becoming a cosmologist, the first step is to get
your bachelor's degree. To prepare yourself for this career, consider
taking undergraduate courses in mathematics, science, philosophy and
astronomy. Majoring in astronomy may help prepare you for a career as a
cosmologist, as it provides you with an introduction to many concepts
and theories that are important in cosmology.
2. Apply for an internship
In the fields of cosmology and astronomy, you may increase your chances
of finding a cosmology-related position if you obtain professional
experience, so consider applying for a cosmology research internship
while obtaining your undergraduate degree. Alternatively, you can pursue
an internship right after you graduate. A cosmology internship might
include helping professors with their research or working in a
laboratory.
A cosmology internship can help you develop a better understanding of
the role and responsibilities of a cosmologist. Internships can also
allow you to network and meet those in the field that might assist you
with future opportunities.
3. Obtain a Ph.D. in a related field
In order to become a professional cosmologist , employers require a
Ph.D. in a related field like physics, mathematics or astronomy. Work as
a cosmologist relies on adequate knowledge in all three fields. This
profession uses advanced mathematics like algebra and calculus, so
consider focusing on these areas while in a graduate program.
In university, you may also want to
familiarize yourself with field-specific concepts like electromagnetism,
quantum mechanics and thermodynamics. Some universities employ
cosmologists to conduct research for the faculty,
so getting your Ph.D. can also help you meet people working as
university researchers that may connect you with professional
opportunities.
4. Find a post-doctorate research position or fellowship
Once you have a Ph.D. in a related field, you're able to apply for
cosmologist positions. However, some employers may prefer a candidate
who has professional experience and academic credentials, which means it
could benefit you to look for a post-doctorate research position or
fellowship. These opportunities allow you to apply your advanced
knowledge and skills in a practical environment. During this time, you
also work with established professionals who can guide your development
and potentially serve as recommenders for any full-time cosmology
positions to which you apply.
Employment Opportunities
Cosmologists can find employment in academia,
with the government and with research groups.
Additionally, both public and private organizations hire cosmologists to
conduct research or help develop products. Some organizations that hire
cosmologists include:
Space education centres
Aerospace companies
Space physics laboratories
Planetariums and observatories
Astronomical equipment manufacturers

You Know? Research within Australia includes: Galaxies and Cosmology The problem of when and how galaxies formed continues to occupy large amounts of telescope and computer simulation time. Galaxies are complex stellar systems with numerous physical processes. These processes include star formation, stellar dynamics, gas dynamics, and includes the role of the dark matter which is their major constituent. Having forming galaxies can interact with their environment and other galaxies. Outright mergers may occur leading to the formation of a new galaxy. Extragalactic research is a dominant theme in Australian astronomy, and is carried out within almost every university and government research group. Groups within Australian that work on galaxies & cosmology include: The Astronomy and Astrophysics group at the Australian National University employ an observational approach to study galaxy morphology and galaxy formation. The twin Gemini telescopes on Mauna Kea and Cerro Pachon enable researchers to look back in time on the formation of other galaxies and compare observations to theoretical models of galaxy formation. The Astrophysics Group at ANU’s Mathematical Sciences Institute are currently involved in using dark matter models of the early universe to study the impact of the first generation of stars and black holes on the re-ionisation of the Universe. This study is expected to elucidate the processes that are important in determining the morphology of the universe as it emerges from the “dark ages”. The group is also involved in investigating the origin of Type Ia Supernovae, and the limitations in their use as standard candles for probing the large scale structure of the universe. The Galaxy formation and Cosmology group at Swinburne University’s Centre for Astrophysics and Supercomputing take a different approach, utilizing advanced computer technology and specially developed computer code to model galactic evolution. They employ a broad range of complementary approaches to modeling the formation of galaxies, each with their own unique strengths including: Collisionless Dark Matter, Adaptive Mesh Refinement, Gravitational Tree N-body + SPH and Semi-Analytical Models. The Extragalactic Group at Swinburne is studying galaxy formation and evolution via observation and modelling. The group regularly obtains observations on some of the world’s best telescopes (including Hubble Space Telescope, Keck, Gemini and Parkes). These observations allow astronomers to probe the role of environment in galaxy evolution, and to identify the epoch of galaxy assembly. The University of Melbourne is engaged in several theoretical investigations of galactic structure, including a first-principles analysis of the statistical mechanics of self-gravitating systems (with implications for the origin of the de Vaucouleurs profile in merger remnants), and the origin of the magnetic field in galaxy clusters (as inferred from Faraday rotation measure data acquired with the VLA and Australia Telescope National Facility). There is also an active program in the study of HI in nearby galaxies, including the determination of the HI mass function, the Tully-Fisher Relation, and the distribution of HI in groups and clusters of galaxies. The group also uses gravitational lensing to study a wide range of topics, including the dark matter halos of galaxies, microlensing and other areas of statistical lensing. The Astrophysics Group at the University of Sydney is using data from SUMSS and NVSS in conjunction with the 2dF and 6dF galaxy redshift surveys, to explore the radio luminosity functions of both AGN and starburst galaxies and their evolution with redshift. SUMSS and NVSS data are also being used, together with optical, infrared and ATCA radio data, to identify and study the most distant and the largest radio galaxies. Analytic calculations, simulations, and observations of gravitational lens systems are all undertaken at the University of Sydney. The lensed sources range from galaxies and quasars, to massive stars and gamma-ray bursters, with the common feature that they are all cosmologically distant. The work is aimed at using gravitational lensing to explore the distant Universe — both the sources in it, and its matter content. In particular, the nature and distribution of the dark matter are key questions which are under investigation. (Source: Astronomy Australia) |
