4 May 2021, 18:41 UTC Venus, aka. Earth’s “Sister Planet,” has always been shrouded in mystery for astronomers. Despite being planet Earth’s closest neighbor, scientists remained ignorant of what Venus’ surface even looked like for well into the 20th century, thanks to its incredibly dense and opaque atmosphere. Even in the age of robotic space exploration, its surface has been all but inaccessible to probes and landers.

Direct link Did you know? The hydrogen in your body was formed in the Big Bang

4 May 2021, 12:43 UTC You may have heard that we are all stardust, but that isn’t strictly true. There are about 20 different elements in the human body, most of which were made inside ancient stars. There’s oxygen, which makes up about half of your body’s mass but only a quarter of its atoms, and then carbon, accounting for another 12 per cent. And just after that, there’s hydrogen, the only element in your body that wasn’t made inside a star long ago and flung into space by a supernova explosion. The hydrogen atoms in your body, accounting for a little over 10 per cent of you, were formed much earlier during the Big Bang, some 13.8 billion years ago.

3 May 2021, 10:57 UTC In the vastness of space, astronomers are likely to find instances of almost every astronomical phenomena if they look hard enough. Many planetary phenomena are starting to come into sharper focus as the astronomy community continues to focus on finding exoplanets. Now a team led by Yifan Zhou at UT Austin has directly imaged a gas giant still in formation.

Direct link Black Hole-Neutron Star Collisions Could Finally Settle the Different Measurements Over the Expansion Rate of the Universe

2 May 2021, 19:56 UTC If you’ve been following developments in astronomy over the last few years, you may have heard about the so-called “crisis in cosmology,” which has astronomers wondering whether there might be something wrong with our current understanding of the Universe. This crisis revolves around the rate at which the Universe expands: measurements of the expansion rate in the present Universe don’t line up with measurements of the expansion rate during the early Universe. With no indication for why these measurements might disagree, astronomers are at a loss to explain the disparity.
