How Far Away is Fusion? Unlocking the Power of the Sun I’d like to think we’re smarter than the Sun. Let’s compare and contrast. Humans, on the one hand, have made enormous advances in science and technology, built cities, cars, computers, and phones. We have split the atom for war and for energy. What has the Sun done? It’s a massive ball of plasma, made up of mostly hydrogen and helium. It just, kind of, sits there. Every now and then it burps up hydrogen gas into a coronal mass ejection. It’s not a stretch to say that the Sun, and all inanimate material inRead More →

Star Should Have Gone Supernova, But it Imploded Into a Black Hole Instead Collapsing stars are a rare thing to witness. And when astronomers are able to catch a star in the final phase of its evolution, it is a veritable feast for the senses. Ordinarily, this process consists of a star undergoing gravitational collapse after it has exhausted all of its fuel, and shedding its outer layers in a massive explosion (aka. a supernova). However, sometimes, stars can form black holes without the preceding massive explosion. This process, what might be described as “going out not with a bang, but with a whimper”, isRead More →

New Zealand’s First Rocket Launch to Space! Earlier this week, the island nation of New Zealand accomplished a historic first. On Wednesday, May 24th at 16:20 p.m. NZST – 00:20 a.m. EDT; May 23rd, 21:20 p.m. PDT – the country joined the small club of nations that have space launch capability. Taking off from a launch pad located on the Mahia Peninsula (on the North Island), the test flight was also a first for the US/NZ-based company Rocket Lab. With the successful launch of their test rocket, Rocket Lab has become the latest aerospace firm to join a burgeoning market, where private companies are ableRead More →

Trump Proposes $19.1 Billion 2018 NASA Budget, Cuts Earth Science and Education NASA acting administrator Robert Lightfoot outlines NASA’s Fiscal Year 2018 budget proposal during a ‘State of NASA’ speech to agency employees held at NASA HQ on May 23, 2017. Credit: NASA TV/Ken Kremer The Trump Administration has proposed a $19.1 Billion NASA budget request for Fiscal Year 2018, which amounts to a $0.5 Billion reduction compared to the recently enacted FY 2017 NASA Budget. Although it maintains many programs, the budget also specifies significant cuts and terminations to NASA’s Earth Science and manned Asteroid redirect mission as well as the complete elimination ofRead More →

Weekly Space Hangout – May 26, 2017: Stephen Petranek and How We’ll Live On Mars Host: Fraser Cain (@fcain) Special Guest: NAT GEO’s Stephen Petranek is the author of How We’ll Live on Mars (TED Books.) Stephen became a reluctant doomsayer when his earliest TED Talk (10 Ways the World Could End) racked up 1.5 million views. But Petranek is, in fact, an optimist who believes that humanity will escape its predicaments — literally. Within a century, he predicts that humans will have established a city of 80,000 on Mars: and that not only is that plausible, but it’s also inevitable. Having worked in publishingRead More →

The Columba Constellation Welcome back to Constellation Friday! Today, in honor of the late and great Tammy Plotner, we will be dealing with the dove – the Columba 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. Since then, thanks to the efforts of astronomer and explorers, many more constellations have come to be recognized. One of these is the constellationRead More →

Mouse Sperm Went to Space and Produced Healthy Mice With proposed missions to Mars and plans to establish outposts on the Moon in the coming decades, there are several questions about what effects time spent in space or on other planets could have on the human body. Beyond the normal range of questions concerning the effects of radiation and lower-g on our muscles, bones, and organs, there is also the question of how space travel could impact our ability to reproduce. Earlier this week – on Monday, May 22nd – a team of Japanese researchers announced findings that could shed light on this question. UsingRead More →

New Ideas for the Mysterious Tabby’s Star: a Gigantic Planet or a Planet With Rings KIC 8462852 (aka. Tabby’s Star) captured the world’s attention back in September of 2015 when it was found to be experiencing a mysterious drop in brightness. A week ago (on May 18th), it was announced that the star was at it again, which prompted observatories from all around the world to train their telescopes on the star so they could observe the dimming as it happened. And just like before, this mysterious behavior has fueled speculation as to what could be causing it. Previously, ideas ranged from transiting comets andRead More →

NASA Moves Up Mission to Metal Asteroid Psyche This illustration depicts the spacecraft of NASA’s Psyche mission orbiting the metal asteroid Psyche (pronounced SY-kee). Solar power with electric propulsion will be used to propel the spacecraft to Psyche. The asteroid’s average distance from the sun is about three times the Earth’s distance or 280 million miles. Credit: SSL/ASU/P. Rubin/NASA/JPL-Caltech I’m getting psyched for Psyche, which is both the name of an asteroid orbiting the sun between Mars and Jupiter and NASA’s mission to the asteroid. Part of the reason for this excitement comes from learning today that NASA has moved up the launch one year toRead More →

New Way to Make Plasma Propulsion Lighter and More Efficient Plasma propulsion is a subject of keen interest to astronomers and space agencies. As a highly-advanced technology that offers considerable fuel-efficiency over conventional chemical rockets, it is currently being used in everything from spacecraft and satellites to exploratory missions. And looking to the future, flowing plasma is also being investigated for more advanced propulsion concepts, as well as magnetic-confined fusion. However, a common problem with plasma propulsion is the fact that it relies on what is known as a “neutralizer”. This instrument, which allows spacecraft to remain charge-neutral, is an additional drain on power. Luckily,Read More →

Scientists Propose a New Kind of Planet: A Smashed Up Torus of Hot Vaporized Rock There’s a new type of planet in town, though you won’t find it in well-aged solar systems like our own. It’s more of a stage of formation that planets like Earth can go through. And its existence helps explain the relationship between Earth and our Moon. The new type of planet is a huge, spinning, donut-shaped mass of hot, vaporized rock, formed as planet-sized objects smash into each other. The pair of scientists behind the study explaining this new planet type have named it a ‘synestia.’ Simon Lock, a graduateRead More →

What is Neptune Made Of? Since it’s discovery in the mid-19th century, Neptune has consistently been a planet of mystery. As the farthest planet from our Sun, it has only been visited by a single robotic mission. And there are still many unanswered questions about what kind of mechanics power its interior. Nevertheless, what we have learned about the planet in the course of the past few decades is considerable. For example, thanks to the Voyager 2 probe and multiple surveys using Earth-based instruments, scientists have managed to gain a pretty good understanding of Neptune’s structure and composition. In addition to knowing what makes upRead More →

We Have More Details on the Outermost Trappist-1 Planet! The announcement of a seven-planet system around the star TRAPPIST-1 earlier this year set off a flurry of scientific interest. Not only was this one of the largest batches of planets to be discovered around a single star, the fact that all seven were shown to be terrestrial (rocky) in nature was highly encouraging. Even more encouraging was the fact that three of these planets were found to be orbiting with the star’s habitable zone. Since that time, astronomers have been seeking to learn all they can about this system of planets. Aside from whether orRead More →

Here’s How We Can Detect Plants on Extrasolar Planets The past year has been an exciting time for those engaged in the hunt for extra-solar planets and potentially habitable worlds. In August of 2016, researchers from the European Southern Observatory (ESO) confirmed the existence of the closest exoplanet to Earth (Proxima b) yet discovered. This was followed a few months later (February of 2017) with the announcement of a seven-planet system around TRAPPIST-1. The discovery of these and other extra-solar planets (and their potential to host life) was an overarching theme at this year’s Breakthrough Discuss conference. Taking place between April 20th and 21st, theRead More →

Do Gravitational Waves Permanently Alter the Nature of Spacetime? On February 11th, 2016, scientists at the Laser Interferometer Gravitational-wave Observatory (LIGO) announced the first detection of gravitational waves. This development, which confirmed a prediction made by Einstein’s Theory of General Relativity a century prior, opened new avenues of research for cosmologists and astrophysicists. It was also a watershed for researchers at Monash University, who played an important role in the discovery. And now, a little over a year later, a team of researchers from the Monash Center for Astrophysics has announced another potential revelation. Based on their ongoing studies of gravitational waves, the team recentlyRead More →
