Why do astronomers sometimes considered

The findings, which are published online and will appear in the April issue of Astrobiology, have the effect of expanding that perceived habitable zone by 10 to 20 percent. And that in turn dramatically increases the number of worlds considered potentially right for life. Such a tilt-a-world becomes potentially habitable because its spin would cause poles to occasionally point toward the host star, causing ice caps to quickly melt.

Barnes is second author on the paper. Hours can be irregular, particularly for observational astronomers and when travel is needed for conferences. Although some astronomers do physically carry out observations overnight, this type of research is increasingly becoming rare.

Often data is collected by remote and space-based telescopes and sent online, allowing the data to be analysed during normal working hours. Almost all astronomy jobs require you to have or be working towards a PhD.

To apply for a PhD, you generally need a or above in any of, but not limited to, the following subjects:. If you're interested in astronomical instrumentation, either for research telescopes or space missions, then engineering degrees are often a prerequisite. It's possible to work in astronomy research with only an undergraduate degree, but to progress you'll need a PhD. Professors in astronomy usually have a PhD but sometimes also several years of postdoctoral positions as well before they land a permanent post.

Funding goes direct to the institution and individual universities will have more information on how funding can be accessed. Be sure to apply early for PhD programs so that departments have time to apply for funding on your behalf. Once you have a PhD, your research supervisor can help you identify possible postdoctoral posts, or you can apply for a fellowship that allows you to carry on independent research.

Generally speaking, a qualified candidate for a permanent academic post will have five to ten years of research experience already, including time working on the PhD and postdoctoral positions. The best way to find out if you're well-suited for a career in research astronomy is to spend time doing research. Many university departments offer summer placements for undergraduate students and you can sometimes be involved with research alongside your studies.

Gaining some work experience at an observatory or astronomical museum would also give you an understanding of how to use equipment and how data is collected. Customer-facing roles would also allow you to gain skills in dealing with and communicating with the public. There are also many other smaller amateur clubs and stargazing organisations in locations across the UK.

The majority of astronomers are employed by universities, but there are a few government and private institutions such as observatories that hire astronomers. Permanent positions in both astronomy research and outreach can be competitive, so you may have to consider moving internationally to pursue this career.

If you're studying for a PhD while employed in a research post, you'll be mentored by your supervisor, who will oversee your research. Which element should formal writing always include.
