There's a Type 1a Supernova in the Making, Just 150 Light-Years Away

Universe Today - Mon, 04/07/2025 - 6:02pm

Astronomers have discovered a remarkable star system just 150 light-years from Earth that's destined for a spectacular cosmic display. The system contains a white dwarf star drawing material from its companion star, with the pair orbiting at just 1/60th of the Earth-Sun distance. With their combined mass reaching 1.56 times that of our Sun, these stars are gradually spiralling toward each other, setting the stage for a spectacular explosion. Fortunately, scientists estimate this cataclysmic event won't occur for roughly 23 billion years, long after our own Sun will have reached the end of its life cycle.

Asteroid 2024 YR4 Won't Hit Earth, But There May Be a Lunar Light Show

Universe Today - Mon, 04/07/2025 - 3:49pm

Although astronomers have ruled out a smash-up between Earth and an asteroid known as 2024 YR4 in the year 2032, the building-sized space rock still has a chance of hitting the moon. In fact, the chances — slight as they are — have doubled in the past month.

Andromeda's Black Hole is Winking at Us

Universe Today - Mon, 04/07/2025 - 2:03pm

Despite their name, black holes can sometimes emit radiation. A team of astronomers has recently detected a flicker of X-ray radiation from the supermassive black hole at the center of the Andromeda Galaxy. This flicker was identified using 15 years of data from the Chandra X-ray Observatory, revealing two distinct flashes in 2006 and 2013. Interestingly, these flashes coincided with bursts of neutrinos detected by the IceCube Neutrino Observatory, offering exciting new insights into the extreme conditions surrounding the black hole.

Terraforming Mars Will Require Hitting It With Mulitple Asteroids

Universe Today - Mon, 04/07/2025 - 1:51pm

Terraforming Mars has been the long-term dream of colonization enthusiasts for decades. But when you start to grapple with the actual physics of what would be necessary to do so, the effort seems further and further out of reach. Depictions like those of Kim Stanley Robinson's Mars Trilogy are just wildly unrealistic regarding the sheer amount of material that must be moved to the Red Planet to achieve anything remotely resembling Earth-like conditions. That is the conclusion of an abstract presented at the 56th Lunar and Planetary Science Conference by Leszek Czechowski of the Polish Academy of Sciences.
