Stars oscillate. Even the Sun does. And we can learn a lot about them by studying those oscillations. How is it done and what can we learn? Finding out in this interview.

Interferometers are a great tool for getting incredible resolution without building giant mirrors. Why don't all telescopes use it? What projects should we expect and what could we get from them? What are the challenges? Find out in this interview!

AI is practically everywhere right now. But what practical use does it have in science? How can machine learning and large language models help in Astronomy and Cosmology? What can they look like and what use can we get out of them?

Satellites run out of fuel and have to de-orbit and end their missions. But what if they had access to a practically infinite amount of fuel? What if they could scoop air from the atmosphere and use it as propellant? That is exactly the research that Dr Mansur…

People always ask me why we’re stuck with chemical rockets. Seriously, exploding a bunch of hydrogen or kerosene is the best we can do?

Good news, there are other, exotic science fiction-sounding propulsion systems out there which use electromagnetic fields…

Space is the worst. It’s got hostile radiation, a total lack of atmosphere, near absolute zero temperatures, problematic gravity wells, and worse.

In order to keep your spacecraft alive in that environment, you need electricity to keep it warm. Not to mention…

This Hubble image features the spiral galaxy Messier 31 (M31). M31 is better known as the Andromeda Galaxy.

An estimated 2 trillion+ galaxies occupy the observable universe.[1]
On the order of 100,000 galaxies make up the Local Supercluster, and about 51 galaxies are in the Local Group (see list of nearest galaxies for a complete list).

I use open-source software like Blender to make these videos. And I support and recommend using the open-source, no-logs, end-to-end encrypted VPN service provided by Proton. Check it out here: https://go.getproton.me/SH2Fi

This compares some of the ringworlds…

supercluster containing the Milky Way and approximately 100,000 other nearby galaxies

Более десяти лет прошло с тех пор, как я ездил в поселок Орево на лабораторки и сборы (перед основными сборами в Балабаново у нас два раза проводились небольшие - пятидневные). Спасибо Александру Шаенко за возможность испытать ностальгию - сегодня в знаменитый…
