18: Neutron stars confirmed as sources of ultraluminous X-rays - SpaceTime with Stuart Gary Series 21 Episode 187 Mar 2018, 09:51 UTC Astronomers have confirmed neutron stars as one of the sources of ultraluminous X rays – powerful beams shining with the light of millions of Suns. The findings have gone some way to solving a long standing galactic mystery.
StarDate Online 6 Mar 2018, 06:00 UTC The night sky is filled with wondrous objects with beautiful names — names from ancient Arabic, Latin, and Greek. But the most prominent object in the night sky doesn’t have one of those names. It’s the Moon — a name that means — well, the Moon. The name is a little more lyrical in other languages — Luna in Spanish, Lune in French — but they all mean the same thing. There’s no real story behind any of them.

StarDate Online 5 Mar 2018, 06:00 UTC The Sun’s closest planets are standing close to each other in the early evening sky right now. They’re bright, but they’re quite low, so you need a clear horizon to spot them. They’ll move higher into the sky over the next few nights, though, making them easier to find.
StarDate Online 4 Mar 2018, 06:00 UTC Many people spend a lot of money on products designed to keep their hair from getting too frizzy. But getting rid of the frizziness just could deprive them of the chance to hear something rare: the crackling of a bright meteor. A meteor forms when a bit of space rock slams into Earth’s atmosphere. Friction causes it to vaporize, creating a streak of light. Bigger rocks form brighter streaks, known as fireballs.
StarDate Online 3 Mar 2018, 06:00 UTC A brilliant streak of light flashed above Long Island on the afternoon of October 18th, startling hundreds of observers. Another one was seen above northern New York a few weeks later. And in early January, yet another one punctuated the night skies of Manitoba and Ontario. All three of these events were fireballs — chunks of space rock burning up as they slammed into Earth’s atmosphere.
SpaceTime with Stuart Gary 2 Mar 2018, 08:24 UTC Astronomers have discovered what might be some of the biggest supermassive black holes ever seen. The new findings follow observations of 72 galaxies in some of the known universe’s brightest and most massive galaxy clusters.
