Usually when astronomers talk about our neighbouring galaxy, they’re talking about Andromeda, which is a cosy 2.5 million light-years away. But just a little farther — OK, 500,000 light-years farther — is another spiral galaxy, the third largest in our local group. Hubble has just released its most detailed view yet of that galaxy, which is known as Triangulum (can you see why?).

One of the year’s most active meteor showers, the Perseids, will peak overnight Sunday into Monday, with 60 to 70 meteors per hour. They aren't visible to most of Australia - only those lucky people on the northern end of Brisbane and above will get the opportunity to glimpse them.
But even so, a lot of Gizmodo readers live in cities. So I wondered — will city dwellers see the meteor shower?
The 21st century’s longest lunar eclipse has passed, eclipse doomsday fever has subsided, and all that’s left are the memories and pictures, which you can find everywhere online. But one image really stood out to us — not because of the way the Moon looked, but because of how it made the Earth look.
Australian amateur astronomer Tom Harradine had always wanted to create an image of the Earth’s umbra, the darkest inner region of the shadow. But during an eclipse, the Moon doesn’t pass through the whole of the Earth’s shadow. He needed a trick in order to show the whole thing.
Amateur astronomer Victor Buso was testing his camera-telescope setup in Argentina back in September 2016, pointing his Newtonian telescope at a spiral galaxy called NGC613. He collected light from the galaxy for the next hour and a half, taking short exposures to keep out the Santa Fe city lights. When he looked at his images, he realised he'd captured a potential supernova - an enormous flash of light and energy bursting off of a distant star.
