Dinosaur Killing Asteroid hit Earth in Exactly the Wrong Spot Sixty-six million years ago, an asteroid struck Earth in what is now the Yucatan Peninsula in southern Mexico. This event, known as the Chicxulub asteroid impact, measured 9 km in diameter and caused extreme global cooling and drought. This led to a mass extinction, which not only claimed the lives of the dinosaurs, but also wiped out about 75% of all land and sea animals on Earth. However, had this asteroid impacted somewhere else on the planet, things could have turned out very differently. According to a new study produced by a team of JapaneseRead More →

NASA Moving Ahead with Deployment of Orion Capsule and Space Launch System On October 11th, 2010, Congress signed the bipartisan NASA Authorization Act, which allocated the necessary funding for the space agency to commence preparations for its “Journey to Mars“. For the sake of mounting the first crewed missions to the Red Planet, several components were designated as being crucial. These included the Space Launch System (SLS) and the Orion Multi-Purpose Crew Vehicle. Despite a recent announcement that NASA would be prioritizing a return to the Moon in the coming years, both the SLS and Orion are on track with the eventual goal of mountingRead More →

Life on Mars can Survive for Millions of Years Even Right Near the Surface Mars is not exactly a friendly place for life as we know it. While temperatures at the equator can reach as high as a balmy 35 °C (95 °F) in the summer at midday, the average temperature on the surface is -63 °C (-82 °F), and can reach as low as -143 °C (-226 °F) during winter in the polar regions. Its atmospheric pressure is about one-half of one percent of Earth’s, and the surface is exposed to a considerable amount of radiation. Until now, no one was certain if microorganismsRead More →

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 →

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 →

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 →

Cutting-Edge Astronomy Confirms Most Ancient Galaxy to Date Since the deployment of the Hubble Space Telescope, astronomers have been able to look deeper into the cosmic web than ever before. The farther they’ve looked, the deeper back in time they are able to see, and thus learn what the Universe looked like billions of years ago. With the deployment of other cutting-edge telescopes and observatories, scientists have been able to learn a great deal more about the history and evolution of the cosmos. Most recently, an international team of astronomers using the Gemini North Telescope in Hawaii were able to spot a spiral galaxy locatedRead More →

Check Out NASA’s New Instrument that will Look for Life on Enceladus Ever since the Cassini mission entered the Saturn system and began studying its moons, Enceladus has become a major source of interest. Once the probe detected plumes of water and organic molecules erupting from the moon’s southern polar region, scientists began to speculate that Enceladus may possess a warm-water ocean in its interior – much like Jupiter’s moon Europa and other bodies in our Solar System. In the future, NASA hopes to send another mission to this system to further explore these plumes and the interior of Enceladus. This mission will likely include aRead More →
