Astrophysics covers a huge amount of scales from subatomic size to the size of the universe. Nevertheless, it is often possible to describe fundamental phenomena only with the help of few equations – although doing the calculations may reveal surprises.
Where are the Sun’s grandparents?
Our Sun’s ancestors are thought to form out of the primordial composition of the early Universe, almost pure hydrogen and helium. How likely are we to observe such stars?
Kepler-167e: The 1st Validated Transiting Jupiter Analog
Look up in the sky. It’s a bird! No, it’s a background eclipsing binary! No, it’s Kepler-167e: the first transiting exoplanet that’s just like Jupiter!!!
Globular Clusters as Cradles of Life and Advanced Civilizations
Could we find advanced civilizations in the globular clusters orbiting the Milky Way galaxy? The authors of today’s astrobite paper think we might…
How to say ‘Hi’ in Alien, and why it’s the worst idea on Earth
Using a laser we can carefully edit the telltale signs of the Earth’s presence, hiding ourselves away or announcing our presence to other life in the universe. But doing so may be fraught with unknowable consequences that we can never undo. Maybe it’s best to just stay behind the galactic sofa.
