Space is really far away, so when you send a satellite out into the void, that’s pretty much the last you’re going to be able to work on it. And if anything goes wrong, too bad, you’re out a satellite. But a new test has shown that it’s possible to actually visit and fix a satellite in space. Maybe we don’t have to throw them all away after all.
As everyone knows, the Universe owes us a bright comet. There have been a lot of promising candidates, but in the end, they always fail to live up to our expectations. Comets keep on breaking up with us.
So much of our Solar System has been shaped by enormous collisions early on in our history. Seriously, the nature of every planet in the Solar System has some evidence of massive impacts during some point in its history.
Last month astronomers announced that they had detected a tiny asteroid that had been captured by the Earth’s gravity well and had been sharing our orbit for a few years. Today, let’s talk about the smallest moons in the Solar System.
White dwarfs are usually about 60% the mass of the Sun, so it was a bit of a surprise when astronomers found one that was almost exactly twice that. What happens when white dwarfs merge?
Fraser and Pamela discuss the coronavirus worldwide pandemic that is upon us. There is much to discuss.
When it comes to telescopes, bigger is better. But bigger is Way more expensive. So astronomers merge the light from several telescopes to act like a much larger telescope.
We lost a bright star here on planet Earth last week. NASA mathematician Katherine Johnson passed away at the age of 101, after an incredible career of helping humans land on the Moon.
You can’t make a Solar System without a whole lot of dust. This dust has blocked astronomers views into some of the most fascinating parts of the cosmos. But new telescopes & techniques are allowing astronomers to peer through this dust, and see these events like never before.
Well, good news! Time to talk about Betelgeuse. Why it might be dimming and what could happen if it explodes as a supernova. #365DaysOfAstro
