We’ve been following this story for more than a decade, so it’s great to finally have an answer to the question, why was supernova 2006gy so insanely bright? Astronomers originally thought it was an example of a supermassive star exploding, but new evidence provides an even more fascinating answer.
Red dwarfs are the longest lived stars in the Universe, the perfect place for life to hang out for trillions of years. But they’re tempestuous little balls of plasma, hurling out catastrophic flares that could wipe away life. Are they good or bad places to live?
Now astronomers can study objects in both visible light, neutrinos, gravitational waves and more. The era of multi-messenger astronomy is here.
There are already 180 Starlinks in orbit, & thousands more are coming. What will be the impact on astronomy & what can we do about it?
In this episode they talk about the issues surrounding the construction of the Thirty Meter Telescope on Mauna Kea.
Let’s take a look at some of the space and astronomy stories we’re looking forward to in 2020. More with @AstronomyCast at #365DaysOfAstro
Today we’re going to talk about some unusual objects astronomers have discovered, and why this number is only going to go way way up.
There are regions which we still haven’t seen: the Cosmic Dark Ages. What’s it going to take to observe some of these earliest moments in the Universe?
Powerful observatories allowing us to see further back in time. But there are regions which we still haven’t seen: the Cosmic Dark Ages. What’s it going to take to observe some of these earliest moments in the Universe?
Last week we gave you an update on the formation of elements from the Big Bang and in main sequence stars like the Sun. This week, we wrap up with a bang, talking about the death of the most massive stars and how they seed the Universe with heavier elements.
