UNAWE Space Scoop - Tiny Black Holes Have Big Superpowers
The 365 Days of Astronomy
Black holes come in many sizes. Small, medium, large & extra large. The size of a black hole mostly depends on how massive the star was before it ran out of fuel, exploded as a supernova and collapsed under its own extreme gravity. The more massive the black hole, the stronger and larger its effect on the fabric of space and time. Here’s the new bit! In a recent study, astronomers found that even tiny black holes have immense power to shape their part of the galaxy. Far more than previously thought. Black holes can rip apart a star that comes too close by. Even the tiniest...

Cheap Astronomy - Dear CA #120: Different Perspectives
The 365 Days of Astronomy
Hosted by Steve Nerlich. Looking askance… Dear Cheap Astronomy – have we got any spacecraft on the other side of the Sun? Well, yes and no. Nearly all our spacecraft orbit the Sun – since they are either orbiting Earth or another planet or are touring the asteroid belt – and hence they’ve all been around the back of the Sun at one time another. The only spacecraft we don’t have orbiting the Sun are the ones on their way out of the Solar System – the Pioneers, the Voyagers and New Horizons, which have sufficient escape velocities to leave solar orbit. Dear Cheap Astronomy...

Exoplanet Radio Ep. 37: Osiris: The Exoplanet That Changed Everything
The 365 Days of Astronomy
Hosted by Tony Darnell. From Oct 2, 2023. The planet is HD 209458 b, and nicknamed "Osiris" after the Egyptian god of the underworld. Osiris is a fitting nickname for this planet, as it is a very hot and hostile world. HD 209458 b orbits its star very closely, and its surface temperature is estimated to be around 1,000 degrees Celsius. This makes it too hot for liquid water to exist on its surface, and it is unlikely to be habitable. Even so, this planet is remarkable in many ways. It occupies first place in a long list of discovery milestones. Get all episodes: Music by...

Today's 2 topics: - Protection against a comet strike is worth considering. Every year, if we are lucky, several comets can come close enough for the Sun to warm and us to see the beautiful changing dust and gas clouds around them with binoculars or our unaided eyes. So far asteroids have gotten most of the attention as dangerous celestial neighbors, however, Dr. Joseph Nuth, a researcher at NASA's...
info_outlineFrom May 21, 2025.
This week, we take a closer look at the weirdly twisty search for a possible planet in our outer solar system. We'll also take in the happy science of aurorae here, at Jupiter, and over Neptune, as well as a bunch of weird discoveries that has some people screaming "It's Aliens!" (it's not aliens).
