A Single Wave, Bigger Than the Milky Way, is Rolling Through the Perseus Galaxy Cluster NASA has discovered a wave of hot gas larger than the Milky Way rolling through the Perseus galaxy cluster. This X-ray image is the result of 16 days of observing with the Chandra X-ray Observatory. The image was filtered to make details easier to see. Credits: NASA’s Goddard Space Flight Center/Stephen Walker et al. An international team of scientists has discovered an enormous wave of hot gas rolling its way through the Perseus galaxy cluster. The wave is a giant version of what’s called a Kelvin-Helmholtz wave. They’re created whenRead More →

Weekly Space Hangout – May 5, 2017: Mathew Anderson’s “Our Cosmic Story,” Updated! Host: Fraser Cain (@fcain) Special Guest: The WSH again welcomes Mathew Anderson, author of “Our Cosmic Story,” to the show. You may recall that Mathew joined us last fall just prior to the release of “Our Cosmic Story,” and he was kind enough to offer our viewers free electronic copies just for the asking. Since then, Mathew has expanded the last chapter of his book to include additional information about SETI, and with the recent exoplanet discoveries, many of the other chapters are of even greater relevance. We are pleased to announceRead More →

The Cetus Constellation Welcome back to Constellation Friday! Today, in honor of the late and great Tammy Plotner, we will be dealing with the sea monster – the Cetus constellation! In the 2nd century CE, Greek-Egyptian astronomer Claudius Ptolemaeus (aka. Ptolemy) compiled a list of all the then-known 48 constellations. This treatise, known as the Almagest, would used by medieval European and Islamic scholars for over a thousand years to come, effectively becoming astrological and astronomical canon until the early Modern Age. One of these constellations is Cetus, which was named in honor of the sea monster from Greek mythology.  Cetus is the fourth largestRead More →

Titan Ripe For Drone Invasion With its dense and hydrocarbon-rich atmosphere, Titan has been a subject of interest for many decades. And with the success of the Cassini-Huygens mission, which began exploring Saturn and its system of moons back in 2004, there are many proposals on the table for follow-up missions that would explore the surface of Titan and its methane seas in greater depth. The challenges that this presents have led to some rather novel ideas, ranging from balloons and landers to floating drones and submarines. But it is the proposal for a “Dragonfly” drone by researchers at NASA’s JHUAPL that seems  particularly adventurous.Read More →

New Japanese mission will be going to the Moons of Mars In the coming decades, the world’s largest space agencies hope to mount some exciting missions to the Moon and to Mars. Between NASA, Roscosmos, the European Space Agency (ESA), the Chinese National Space Agency (CNSA) and the Indian Space Research Organization (ISRO), there is simply no shortage of proposals for Lunar bases, crewed missions to Mars, and robotic explorers to both. However, the Japanese Aerospace Exploration Agency (JAXA) has a different mission in mind when it comes to the coming decades. Instead of exploring the Moon or Mars, they propose exploring the moons ofRead More →

Enjoy The Biggest Infrared Image Ever Taken Of The Small Magellanic Cloud Without All That Pesky Dust In The Way The Small Magellanic Cloud (SMC) galaxy. Credit: ESA/VISTA The Small Magellanic Cloud (SMC) is one of the Milky Way’s nearest companions (along with the Large Magellanic Cloud.) It’s visible with the naked eye in the southern hemisphere. A new image from the European Southern Observatory’s (ESO) Visible and Infrared Survey Telescope for Astronomy (VISTA) has peered through the clouds that obscure it and given us our biggest image ever of the dwarf galaxy. The SMC contains several hundred million stars, is about 7,000 light yearsRead More →

Building Rovers That Can Detect Life and Sequence DNA on Other Worlds In 2015, then-NASA Chief Scientist Ellen Stofan stated that, “I believe we are going to have strong indications of life beyond Earth in the next decade and definite evidence in the next 10 to 20 years.” With multiple missions scheduled to search foe evidence of life (past and present) on Mars and in the outer Solar System, this hardly seems like an unrealistic appraisal. But of course, finding evidence of life is no easy task. In addition to concerns over contamination, there is also the and the hazards the comes with operating inRead More →

Why Do Rockets Need Stages? The Quest to Build a Single Stage to Orbit (SSTO) Now, don’t get me wrong, Science Fiction is awesome. Like almost everyone working in the field of space and astronomy, I was deeply influenced by science fiction. For me, it was Star Trek and Star Wars. I had a toy phaser that made this awesome really loud phaser sound, and I played with it non-stop until it disappeared one day. And I was sure I’d left it in the middle of my floor, like I did with all my toys, but I found it a few years later, hidden upRead More →

Comet Halley Plays Bit Part In Weekend Eta Aquarid Meteor Shower Watch for the Eta Aquarid shower this week, so called because meteors will appear to radiate from near the star Eta Aquarii.  The meteors originate from fragments of Halley’s Comet strewn about its orbit. Every May, Earth crosses the stream and we get a meteor shower. At maximum on Saturday morning May 6, 25-30 meteors per hour might be seen from the right location under dark skies. Map: Bob King, Source: Stellarium Halley’s Comet may be at the far end of its orbit 3.2 billion miles (5.1 billion km) from Earth, but this week fragments ofRead More →

Where Should We Look For Ancient Civilizations in the Solar System? The search for life in the Universe takes many paths. There’s SETI, or the Search for Extraterrestrial Intelligence, which is searching for signals from a distant ancient civilization. There’s the exploration of our own Solar System, on Mars, or underneath the subsurface oceans of Europa and Enceladus, to see if life can be anywhere there’s liquid water and a source of energy. And upcoming space telescopes like James Webb will attempt to directly image the atmospheres of distant extrasolar planets, to see if they contain the distinct chemical signatures of life. But according toRead More →

Rise Of The Super Telescopes: The Wide Field Infrared Survey Telescope We humans have an insatiable hunger to understand the Universe.

NASA’s Space Chainmail to Give Astronauts the Edge in Space Duels One would think NASA was preparing for a some sword fights in space! At least, that’s the impression one might get when they see the new armor NASA is developing for the first time. Officially, they are referring to it as a new type of “space fabric“, one which will provide protection to astronauts, spaceships and deployable devices. But to the casual observer, it looks a lot like chain mail armor! The new armor is the brainchild of Polit Casillas, a systems engineer from NASA’s Jet Propulsion Laboratory. Inspired by traditional textiles, this armorRead More →

What’s that Strange Glowing Mold? Astronauts will Soon be Able to Sequence Unknown Space Organisms Seeking to understand more about space-born microbes, NASA has initiated a program known as Genes in Space-3 – a collaborative effort that will prepare, sequence and identify unknown organisms, entirely from space. For those who might be thinking that this sounds a lot like the film Life – where astronauts revive an alien organism on the International Space Station and everyone dies! – rest assured, this is not the setup for some horror movie. In truth, it represents a game-changing development that builds on recent accomplishments, where DNA was firstRead More →

An Aging Pulsar has Captured a new Companion, and it’s Spinning back up Again When massive stars reach the end of their life cycle, they explode in a massive supernova and cast off most of their material. What’s left is a “milliscond pulsar”, a super dense, highly-magnetized neutron star that spins rapidly and emit beams of electromagnetic radiation. Eventually, these stars lose their rotational energy and begin to slow down, but they can speed up again with the help of a companion. According to a recent study, an international team of scientists witnessed this rare event when observing an ultra-slow pulsar located in the neighboringRead More →
