TRAPPIST-1 System Ideal For Life Swapping Back in February of 2017, NASA announced the discovery of a seven-planet system orbiting a nearby star. This system, known as TRAPPIST-1, is of particular interest to astronomers because of the nature and orbits of the planets. Not only are all seven planets terrestrial in nature (i.e. rocky), but three of the seven have been confirmed to be within the star’s habitable zone (aka. “Goldilocks Zone”). But beyond the chance that some of these planets could be inhabited, there is also the possibility that their proximity to each other could allow for life to be transferred between them. ThatRead More →

Pardon My Vomit: Zero G Ettiquette In the Age Of Space Tourism It’s a new era for space travel. And if there’s one thing that sets it apart from the previous one, it is the spirit of collaboration that exists between space agencies and between the public and private sector. And with commercial aerospace (aka. NewSpace) companies looking to provide everything from launch services to orbital and lunar tourism, a day is fast-approaching when ordinary people will be able to go into space. Because of this, many aerospace companies are establishing safety and training programs for prospective clients. If civilians plan on going into space,Read More →

A Survivor’s Tale: Cassini Lives Through First Ring Dive One down, twenty-one to go! The Cassini spacecraft survived the first dive through the narrow gap between Saturn and its rings, and is now back communicating with Earth. It was a long day for Cassini scientists and engineers at the Jet Propulsion Laboratory while the spacecraft was out of contact for 20 hours during this first dive, signaling the beginning of the end for Cassini. “No spacecraft has ever been this close to Saturn before. We could only rely on predictions, based on our experience with Saturn’s other rings, of what we thought this gap betweenRead More →

Europe & China Discuss Moonbase Partnership In recent years, multiple space agencies have shared their plans to return astronauts to the Moon, not to mention establishing an outpost there. Beyond NASA’s plan to revitalize lunar exploration, the European Space Agency (ESA), Rocosmos, and the Chinese and Indian federal space agencies have also announced plans for crewed missions to the Moon that could result in permanent settlements. As with all things in this new age of space exploration, collaboration appears to be the key to making things happen.  This certainly seems to be the case when it comes to the China National Space Administration (CNSA) andRead More →

What Are Fast Radio Bursts? You might think you’re reading an educational website, where I explain fascinating concepts in space and astronomy, but that’s not really what’s going on here. What’s actually happening is that you’re tagging along as I learn more and more about new and cool things happening in the Universe. I dig into them like a badger hiding a cow carcass, and we all get to enjoy the cache of knowledge I uncover. Okay, that analogy got a little weird. Anyway, my point is. Squirrel! Fast radio bursts are the new cosmic whatzits confusing and baffling astronomers, and now we get toRead More →

Is Another Universe Sitting Too Close To Us On The Multiverse Bus? Since the 1960s, astronomers have been aware of the electromagnetic background radiation that pervades the Universe. Known as the Cosmic Microwave Background, this radiation is the oldest light in the Universe and what is left over from the Big Bang. By 2004, astronomers also became aware that a large region within the CMB appeared to be colder than its surroundings. Known as the “CMB Cold Spot”, scientists have puzzled over this anomaly for years, with explanations ranging from a data artifact to it being caused by a supervoid. According to a new studyRead More →

The Next Pluto Mission: An Orbiter and Lander? For decades, we could only imagine what the view of Pluto’s surface might be. Now, we have the real thing. The images and data from the ” target=”_blank”>New Horizons’ mission flyby of Pluto in July 2015 showed us an unexpectedly stunning and geologically active world. Scientists have used words like ‘magical,’ ‘breathtaking’ and ‘scientific wonderland’ to describe the long-awaited close-up views of distant Pluto. Even though scientists are still analyzing the data from New Horizons, ideas are starting to formulate about sending another spacecraft to Pluto, but with a long-term orbiter mission instead of a quick flyby.Read More →

Designing The Hanging Gardens Of Mars NASA is all about solving challenges, and the goal of having a prolonged presence in space, or a colony on Mars or some other world, is full of challenges, including the necessity of growing food. Scientists at Kennedy Advanced Life Support Research are working on the Prototype Lunar/Mars Greenhouse Project to try and meet that challenge. The Prototype Lunar/Mars Greenhouse Project (PLMGP) is all about growing vegetables for astronauts during extended stays on the Moon, on Mars, or anywhere they can’t be resupplied from Earth. Beyond growing food, the Project aims to understand how food-growing systems can also beRead More →

Did A Comet Impact Push Humans Into Technological Overdrive? About 14,500 years ago, Earth began transitioning from its cold, glacial self to a warmer interglacial state. However, partway through this period, temperatures suddenly returned to near-glacial conditions. This abrupt change (known as the Younger Dryas period) is believed by some to be the reason why hunter-gatherers started forming sedentary communities, farming, and laying the groundwork for civilization as we know it – aka. the Neolithic Revolution. For over a decade, there have been scientists who have argued that this period the result of a comet hitting Earth. Known as the Younger Dryas Impact Hypothesis (aka.Read More →

Meet Steve, A Most Peculiar Aurora Nicknamed Steve, this unusual aurora feature is a 15.5-mile-wide (25 km) ribbon of hot gas flowing westward at about 13,300 mph, more than 600 times faster than the surrounding air. The photo was taken last fall. Copyright: Instagram.com/davemarkelphoto This remarkable image was captured last fall by Dave Markel, a photographer based in Kamloops, British Columbia. Later, aurora researcher Eric Donovan of the University of Calgary, discovered Markel’s strange ribbon of light while looking through photos of the northern lights on social media. Knowing he’d found something unusual, Donovan worked sifted through data from the European Space Agency’s Swarm magnetic field missionRead More →

Adieu Titan: So Long & Thanks For All The Hydrocarbons The Cassini spacecraft has done some amazing things since it arrived in the Saturn system in 2004. In addition to providing valuable information on the gas giant and its system of rings, it has also provided us with extensive data and photographs of Saturn’s many moons. Nowhere has this been more apparent than with Saturn’s largest moon, the hydrocarbon-rich satellite known as Titan. And with just a few hours left before Cassini makes its final plunge between Saturn and its innermost ring (something that no other spacecraft has ever done), we should all take thisRead More →

Another Strange Discovery From LHC That Nobody Understands There are some strange results being announced in the physics world lately. A fluid with a negative effective mass, and the discovery of five new particles, are all challenging our understanding of the universe. New results from ALICE (A Large Ion Collider Experiment) are adding to the strangeness. ALICE is a detector on the Large Hadron Collider (LHC). It’s one of seven detectors, and ALICE’s role is to “study the physics of strongly interacting matter at extreme energy densities, where a phase of matter called quark-gluon plasma forms,” according to the CERN website. Quark-gluon plasma is aRead More →

Messier 40 – the Winnecke 4 Double Star Welcome back to Messier Monday! In our ongoing tribute to the great Tammy Plotner, we take a look at the double star known as Messier 40. Enjoy! During the 18th century, famed French astronomer Charles Messier noted the presence of several “nebulous objects” in the night sky. Having originally mistaken them for comets, he began compiling a list of them so that others would not make the same mistake he did. In time, this list (known as the Messier Catalog) would come to include 100 of the most fabulous objects in the night sky. One of theseRead More →

What is the Average Surface Temperature of Mercury? Of all the planets in the Solar System, Mercury is the closest to our Sun. As such, you would think it is the hottest of all the Solar planets. But strangely enough, it is not. That honor goes to Venus, which experiences an average surface temperature of 750 K (477 °C; 890 °F). Not only that, but Mercury is also cold enough in some regions to maintain water in ice form. Overall, Mercury experiences considerable variations in temperatures, ranging from the extremely hot to the extremely cold. All of this arises from the fact that Mercury hasRead More →
