Gaia is an Even More Powerful Planet Hunter Than we Thought

Utilizing tools for purposes they weren’t initially intended for is a strength of the astronomical community. Scrounging through data collected for one purpose and looking for hints of another seems to be a favorite pastime of many a professional astronomer. That tradition is alive and well, with a team reanalyzing the first few data sets …

Voyager 1 Doesn’t Know Where it is, Generating Random-Looking Telemetry Data

Old computer systems have a lot of wacky ways to fail. Computers that are constantly blasted by radiation have even more wacky ways to fail. Combine those two attributes, and eventually, you’re bound to have something happen. It certainly seems to have with Voyager 1. The space probe, which has been in active service for …

The Building Blocks for Supermassive Black Holes are Found in Dwarf Galaxies

We all know that a humongous black hole exists at the center of our galaxy. It’s called Sagittarius A* (Sgr A* for short) and it has the mass of 4 million suns. We’ve got to see a radio image of it a few weeks back, showing its accretion disk. So, we know it’s there. Astronomers …

“Wind-Ruffled Waves, Foam and Wave Shadows, Above Natural Blue Seawater.” This is how we’ll Spot Exoplanets With Oceans

Our planet’s oceans generate tell-tale light signatures when sunlight reflects off them. Exoplanets with significant ocean coverage may do the same. Can we use the Earth’s reflectance signatures to identify other Earth-like worlds with large oceans? We should be able to, eventually. A new study examined light signatures reflecting off of Earth’s oceans and explored …

Solar Orbiter’s Pictures of the Sun are Every Bit as Dramatic as You Were Hoping

On March 26th, the ESA’s Solar Orbiter made its closest approach to the Sun so far. It ventured inside Mercury’s orbit and was about one-third the distance from Earth to the Sun. It was hot but worth it. The Solar Orbiter’s primary mission is to understand the connection between the Sun and its heliosphere, and …

The Moon’s Ancient Volcanoes Could Have Created Ice Sheets Dozens of Meters Thick

Everyone loves looking at the Moon, especially through a telescope. To see those dark and light patches scattered across its surface brings about a sense of awe and wonder to anyone who looks up at the night sky. While our Moon might be geologically dead today, it was much more active billions of years ago …

Spacesuits are Leaking Water and NASA is Holding off any Spacewalks Until They can Solve the Problem

NASA’s spacesuits are getting old. The extra-vehicular mobility units – EMUs for short – were designed and built for spacewalks outside NASA’s space shuttles, which flew for the last time in 2011. Nowadays, the EMUs are an integral part of maintaining and upgrading the International Space Station (ISS) exterior, providing the crew with the ability …
