The Intense Heat from the Sun Helps Ice Form on Mercury. Wait… What? While the scorching planet Mercury might not be the first place you’d think to look for ice, the MESSENGER mission confirmed in 2012 that the planet closest to the Sun does indeed hold water ice in the permanently-shadowed craters around the Mercury’s poles.  But now a new study regarding Mercury’s ice provides even more counter-intuitive … Continue reading “The Intense Heat from the Sun Helps Ice Form on Mercury.

Greenland and Antarctica are Losing Their Ice 6 Times Faster than in the 1990s Is anybody listening? Smart people tell us that when it comes to conveying the reality of climate change, and the threat it poses, people don’t respond to facts. We respond to stories and narratives. We’re a narrative-driven species. But at Universe Today we know that facts underlie every good story. And the facts regarding ice … Continue reading “Greenland and Antarctica are Losing Their Ice 6 Times Faster than in the 1990s” The post Greenland and Antarctica are Losing Their Ice 6 Times Faster than in the 1990s appeared first onRead More →

Your Umbrella is Insufficient on a Planet Where it Rains Iron Imagine a planet where it rained iron. Sounds impossible. But on one distant exoplanet, which is tidally locked to its star, the nightside has to contend with a ferrous downpour. The planet is called WASP-76b and it’s about 390 light years away from us in the constellation Pisces. It was discovered in 2013, and it’s the … Continue reading “Your Umbrella is Insufficient on a Planet Where it Rains Iron” The post Your Umbrella is Insufficient on a Planet Where it Rains Iron appeared first on Universe Today.

Slime Mold Grows the Same as the Large Scale Structure of the Universe Matter in the Universe is not distributed equally. It’s dominated by super-clusters and the filaments of matter that string them together, surrounded by huge voids. Galaxy super-clusters are at the top of the hierarchy. Inside those is everything else: galaxy groups and clusters, individual galaxies, and solar systems. This hierarchical structure is called the “Cosmic … Continue reading “Slime Mold Grows the Same as the Large Scale Structure of the Universe” The post Slime Mold Grows the Same as the Large Scale Structure of the Universe appeared first on Universe Today.

Neutron Star Measures Just 22 Kilometers Across How big is a neutron star? These extreme, ultra-dense collapsed stars are fairly small, as far as stellar objects are concerned. Even though they pack the mass of a full-sized star, their size is often compared to the width of a medium-to-large-sized city. For years, astronomers have pegged neutron stars at somewhere between 19-27 km … Continue reading “Neutron Star Measures Just 22 Kilometers Across” The post Neutron Star Measures Just 22 Kilometers Across appeared first on Universe Today.

It Looks Like Betelgeuse was Dimming Because it was Dusty After All It’s been said that dust built the Universe. And it turns out dust may be the culprit for building up what are likely false hopes of soon witnessing a massive supernova for the star Betelgeuse. Late last year, both amateur and professional astronomers noticed that the red supergiant star Betelgeuse dimming quickly and significantly, with … Continue reading “It Looks Like Betelgeuse was Dimming Because it was Dusty After All” The post It Looks Like Betelgeuse was Dimming Because it was Dusty After All appeared first on Universe Today.
