Building Electronics That Can Work on Venus The weather on Venus is like something out of Dante’s Inferno. The average surface temperature – 737 K (462 °C; 864 °F) – is hot enough to melt lead and the atmospheric pressure is 92 times that of Earth’s at sea level (9.2 Mbar). For this reason, very few robotic missions have ever made it to the surface of Venus, and those that have did not last long – ranging from about 20 minutes to just over two hours. Hence why NASA, with an eye to future missions, is looking to create robotic missions and components that canRead More →

A Brown Dwarf Prevented a Regular Star from Going Through its Full Life Cycle Eclipsing binary star systems are relatively common in our Universe. To the casual observer, these systems look like a single star, but are actually composed of two stars orbiting closely together. The study of these systems offers astronomers an opportunity to directly measure the fundamental properties (i.e. the masses and radii) of these systems respective stellar components. Recently, a team of Brazilian astronomers observed a rare sight in the Milky Way – an eclipsing binary composed of  a white dwarf and a low-mass brown dwarf. Even more unusual was the factRead More →

Astronomers Practice Responding to a Killer Asteroid” Beyond the Earth-Moon system, thousands of asteroids known as Near-Earth Objects (NEOs) are known to exist. These rocks periodically cross Earth’s orbit and make close a flyby of Earth. Over the course of millions of years, some even collide with the Earth, causing mass extinctions. Little wonder then why NASA’s Center for Near Earth Object Studies (CNEOS) is dedicated to monitoring the larger objects that occasionally come close to our planet. One of these objects is 2012 TC4, a small and oblong-shaped NEO that was first spotted in 2012 during a close flyby of Earth. During its mostRead More →

(Phys.org)—John Chambers, a planetary scientist with the Department of Terrestrial Magnetism at Carnegie Institution has suggested a new theory regarding the formation of gas giant planets. In his paper uploaded to the preprint server arXiv, soon to be published in the Astrophysical Journal, he describes his theory and its possible implications. Powered by WPeMaticoRead More →

Carnival of Space #534 This week’s Carnival of Space is hosted by Allen Versfeld at his Urban Astronomer blog. Click here to read Carnival of Space #534. And if you’re interested in looking back, here’s an archive to all the past Carnivals of Space. If you’ve got a space-related blog, you should really join the carnival. Just email an entry to carnivalofspace@gmail.com, and the next host will link to it.

Proxima Centauri has a Cold Dust Belt that Could Indicate Even More Planets Proxima Centauri, in addition to being the closest star system to our own, is also the home of the closest exoplanet to Earth. The existence of this planet, Proxima b, was first announced in August of 2016 and then confirmed later that month. The news was met with a great deal of excitement, and a fair of skepticism, as numerous studies followed t were dedicated to determining if this planet could in fact be habitable. Another important question has been whether or not Proxima Centauri could have any more objects orbiting it.Read More →

They Just Began Casting the Giant Magellan Telescope’s 5th Mirror. What a Monster Job. The fifth mirror for the Giant Magellan Telescope (GMT) is now being cast, according to an announcement from the Giant Magellan Telescope Organization (GMTO), the body behind the project. The GMT is a ground-breaking segmented telescope consisting of 7 gigantic mirrors, and is being built at the Las Campanas Observatory, in Atacama, Chile. The mirrors for the GMT are being cast at the Richard F. Caris Mirror Laboratory, at the University of Arizona. This lab is the world centre when it comes to building large mirrors for telescopes. But in aRead More →

A giant collision of several galaxy clusters, each containing hundreds of galaxies, has produced this spectacular panorama of shocks and energy. The collisions generated shock waves that set off a celestial fireworks display of bright radio emission, seen as red and orange. In the center of the image, the purple indicates X-rays caused by extreme heating. Powered by WPeMaticoRead More →

Black holes make for a great space mystery. They’re so massive that nothing, not even light, can escape a black hole once it gets close enough. A great mystery for scientists is that there’s evidence of powerful jets of electrons and protons that shoot out of the top and bottom of some black holes. Yet no one knows how these jets form.

(Phys.org)—Mexican astronomers report the discovery of seven new large extragalactic radio sources called giant radio galaxies (GRG). The GRGs were found by visual inspection of radio images provided by two astronomical radio surveys. The findings were presented October 31 in a paper published on arXiv.org.

A Chalmers-led team of astronomers has for the first time observed details on the surface of an aging star with the same mass as the sun. ALMA’s images show that the star is a giant, its diameter twice the size of Earth’s orbit around the sun; they report that the star’s atmosphere is affected by powerful, unexpected shock waves. The research was published in Nature Astronomy. Powered by WPeMaticoRead More →

New Study Says Enceladus had Internal Ocean for Billions of Years When the Cassini mission arrived in the Saturn system in 2004, it discovered something rather unexpected in Enceladus’ southern hemisphere. From hundreds of fissures located in the polar region, plumes of water and organic molecules were spotted periodically spewing forth. This was the first indication that Saturn’s moon may have an interior ocean caused by hydrothermal activity near the core-mantle boundary. According to a new study based on Cassini data, which it obtained before diving into Saturn’s atmosphere on September 15th, this activity may have been going on for some time. In fact, theRead More →

Messier 59 – the NGC 4621 Elliptical Galaxy Welcome back to Messier Monday! Today, we continue in our tribute to our dear friend, Tammy Plotner, by looking at the spiral galaxy known as Messier 59. In the 18th century, while searching the night sky for comets, French astronomer Charles Messier kept noting the presence of fixed, diffuse objects he initially mistook for comets. In time, he would come to compile a list of approximately 100 of these objects, hoping to prevent other astronomers from making the same mistake. This list – known as the Messier Catalog – would go on to become one of theRead More →
