We believe these heavier elements formed in stars, but which stars? And at what points in their lives? Today we’ll update our knowledge with the latest science.
Few sciences have been able to take advantage of the power of computers like astronomy. But with all this computing power, you might be surprised to learn how important a role humans still play in this science.
Proving that there’s alien life on another world is to look for biosignatures, but it looks like there are natural sources that could explain almost any chemical we could hope to search for.
Things used to be so simple. Comets were snowballs from the outer Solar System, and asteroids were rocks from the inner Solar System. But now everything’s all shades of grey. Astronomers have found asteroids that behave like comets and comets that behave like asteroids.
Proving, once & for all that there’s alien life on another world. It should be straightforward, look for biosignatures, but it looks like there are natural sources that could explain almost any chemical we could hope to search for.
Our series on Universe weirdness marches on. This week we take a look at the habitable zone, and how things aren’t as simple as we thought.
Our series on Universe weirdness continues, this time we learn how astronomers are struggling to make sense of the age of the Universe.
Astronomers have been trying to accurately measure the expansion rate of the Universe. It’s been tough to nail down, and now astronomers are starting to figure out why.
Weird Issues: How Do (or Don’t) Planets Form? Hot jupiters? Pulsars with planets? We’re now decades into this planets discovery & the Universe is continuing to surprise us. #365DaysOfAstro
How old are Saturn’s rings? They could be brand new, or they could be as ancient as the Solar System itself. more at #365DaysOfAstro
