The best observations yet of a mysterious gas cloud that was heading for the black hole at the hear of our Milky Way reveal it may have more stellar origins.
The universe is such a big place that it is easy to get baffled by the measurements that astronomers make. The size of UY Scuti, possibly one of the largest stars we have observed to date, is certainly…
A detailed study of comets orbiting the young nearby star Beta Pictoris is published today in the journal Nature, and it reveals striking similarities to the comets found in our solar system. Over the…
What makes our sun shine has been a mystery for most of human history. Given our sun is a star and stars are suns, explaining the source of the sun’s energy would help us understand why stars shine. An…
An American telescope has detected a white dwarf star with a diamond core that could be the coldest of its kind ever discovered…
How are stars formed? What are they made of? And what happens to them when they die? In this week’s TCTV, astrophysicist Akila Jeeson-Daniel explains the physics behind the balls of gas that light up the…
A team of international astronomers has developed a more precise way to deduce the ages of stars and to pinpoint when our…
There is a myth that goldfish have a three-second memory, and I sometimes wonder if the same is true about the part of the human mind that deals with science in the news. This week, the international media…
The sun is our nearest star and the source of all our light and heat on Earth but recent reports have highlighted an ongoing steep decline in solar activity. This story is a reminder that our sun is a…
If you live in the southern hemisphere, you now can safely view the aftermath of a nuclear explosion from the comfort of your own backyard. Just last week a new “star”, Nova Centauri 2013, was discovered…
Galaxies located in groups may be running out of gas, according to a new international study led by Swinburne University…
Twinkle, twinkle, little star, how I wonder what you are. If we look up at the sky at night, we see millions of tiny diamond-like stars. These are actually balls of plasma (very hot gas) consisting of…
Being spiral in shape, our Galaxy is already in permanent rotational motion. But astronomers have found that the Milky Way…
Astronomers have found a small star (a pulsar called PSR J1824-2452I) undergoing a radical transformations. The pulsar’s…
The current theory of star formation has a problem: it cannot make big stars. In the standard star-making recipe, stars are formed in the depths of gas clouds made from molecular hydrogen. These clouds…
Space is Big. Really Big. The Hitchhiker’s Guide to the Galaxy pretty much nailed space with those five words. And space is so really big that our earthly measures of distance struggle. The distance to…
My colleagues and I have confirmed the existence of a new type of star cluster – as published recently in Monthly Notices of the Royal Astronomical Society. But what are star clusters, and why do they…
It was written in the stars all along, but we’ve just found out: a whopping 70% of stars in a widely-studied cluster die before reaching old age which, for stars, is the most productive stage of their…
Astrophysicists from Monash University have found that stars with a high sodium content die before reaching their final life…
