Distance & Speed Of Sun’s Orbit Around Galactic Centre Measured In 2013, the European Space Agency deployed the long-awaited Gaia space observatory. As one of a handful of next-generation space observatories that will be going up before the end of the decade, this mission has spent the past few years cataloging over a billion astronomical objects. Using this data, astronomers and astrophysicists hope to create the largest and most precise 3D map of the Milky Way to date. Though it is almost to the end of its mission, much of its earliest information is still bearing fruit. For example, using the mission’s initial data release,Read More →

Through The Nuclear Looking Glass: The Moon & The Bomb For centuries, scientists have been attempting to explain how the Moon formed. Whereas some have argued that it formed from material lost by Earth due to centrifugal force, others asserted that a performed Moon was captured by Earth’s gravity. In recent decades, the most widely-accepted theory has been the Giant-impact hypothesis, which states that the Moon formed after the Earth was struck by a Mars-sized object (named Theia) 4.5 billion years ago. According to a new study by an international team of researchers, the key to proving which theory is correct may come from theRead More →

Asteroid 2017 BQ6 Looks Like A Brick   This composite of 25 images of asteroid 2017 BQ6 was generated with radar data collected using NASA’s Goldstone Solar System Radar in California’s Mojave Desert. It sped by Earth on Feb. 7 at a speed of around  25,560 mph (7.1 km/s) relative to the planet. The images have resolutions as fine as 12 feet (3.75 meters) per pixel. Credit: NASA/JPL-Caltech/GSSR To radar imager Lance Benner at JPL in Pasadena, asteroid 2017 BQ6 resembles the polygonal dice used in Dungeons and Dragons. But my eyes see something closer to a stepping stone or paver you’d use to build a walkway.Read More →

91 Astronomers Combine 1000 Images Into One Amazing Journey to Jupiter A renewed era of space exploration is underway. Compared to the Space Race of the 20th century, which was characterized by two superpowers locked in a game of “getting there first”, the new era is defined predominantly by cooperation and open participation. One way in which this is evident is the role played by “citizen scientists” and amateur astronomers in exploration missions. Consider the recently-released short film titled “A Journey to Jupiter” by Peter Rosen – a photographer and digital artist in Stockholm, Sweden. Using over 1000 images taken by amateur planetary photographers fromRead More →

What is the Surface Area of the Earth? Whoever coined the phrase “it’s a small world” obviously never tried to travel around it! In truth, the planet’s dimensions are quite impressive, and determining just how big it is took many thousands of years. From astronomers determining that Earth was in fact round (and not a flat disc, cube or ziggurat), to the first successful attempts at circumnavigation, our estimates have changed over time. And in the era of modern astronomy, improvements in instrumentation, methodology, and the ability to see Earth from space have certainly helped. According to modern estimates, the surface area of the EarthRead More →

The Centaurus Constellation Welcome back to Constellation Friday! Today, in honor of the late and great Tammy Plotner, we will be dealing with the “Centaur”, the Centaurus 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 is the famous Centaur of classical antiquity, otherwise known as the constellation Centaurus. As one of the 48 constellation included in theRead More →

Time To Build A Venus Rover Venus is often described as being hell itself, because of its crushing pressure, acidic atmosphere, and extremely high temperatures. Dealing with any one of these is a significant challenge when it comes to exploring Venus. Dealing with all three is extremely daunting, as the Soviet Union discovered with their Venera landers. Actually, dealing with the sulphuric rain is not too difficult, but the heat and the pressure on the surface of Venus are huge hurdles to exploring the planet. NASA has been working on the Venus problem, trying to develop electronics that can survive long enough to do usefulRead More →

Watch the Curiosity Rover Roll Across Mars’ Surface We all love the ‘selfies’ the Curiosity rover takes of itself sitting on Mars. We love them because it’s so amazing to see a human-made object on another world, and these images give us hope that one day we might have pictures of ourselves standing on the surface of the Red Planet. But wouldn’t it be great if we see Curiosity ‘in action’ on Mars, and be like a fly on a rock, watching the rover roll past us? Thanks to graphic artist Seán Doran, we can do just that. Take a look at this absolutely amazingRead More →

Plans call for the commercial airlock to be launched on a commercial cargo vesselRead More →

Can We Launch Nuclear Waste Into the Sun? When I look at the Sun, I don’t see a warm life-giving orb, nourishing all living creatures here on Earth. No, I see that fiery ball as a cosmic garbage compactor. A place I can dump all my household garbage, to make room for new impulse purchases. I mean, the Sun is right there, not doing anything right? It’s hotter than any garbage incinerator, and it’s the gravitational well at the heart of the Solar System. Get me a rocket, let’s blast that waste into oblivion. Okay, I suspect it’s going to get expensive, so let’s justRead More →

Image credit and copyright: Lucca Ruggiero In the southern hemisphere this weekend in the ‘Land of Oz?’ Are you missing out on the passage of Comet 45/P Honda-Mrkos-Pajdušáková, and the penumbral lunar eclipse? Fear not, there’s an astronomical event designed just for you, as the Moon occults (passes in front of) the bright star Regulus on the evening of Saturday, January 11th. The entire event is custom made for the continent of Australia and New Zealand, occurring under dark skies. Now for theRead More →

The Magellenic Clouds Stay Connected By A String Of Stars Astronomers have finally observed something that was predicted but never seen: a stream of stars connecting the two Magellanic Clouds. In doing so, they began to unravel the mystery surrounding the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC). And that required the extraordinary power of the European Space Agency’s (ESA) Gaia Observatory to do it. The Large and Small Magellanic Clouds (LMC and SMC) are dwarf galaxies to the Milky Way. The team of astronomers, led by a group at the University of Cambridge, focused on the clouds and on one particularRead More →

Uber Brings In NASA Engineer To Build Flying Cars Flying cars have become something of a hot ticket item of late. In the past few years, companies like Terrafugia, Aeromobil and Moller International have all grabbed headlines with their particular designs. And soon enough, international transportation giant Uber could be joining the ranks of those looking to turn a popular staple of science fiction into science fact. In a move to expand their ride-sharing services to the skies, the company recently hired NASA aerospace engineer Mark D. Moore to spearhead Uber Elevate. For 30 years, Moore has worked for NASA, researching advanced aircraft and technologiesRead More →

31 Years After Disaster, Challenger Soccer Ball Finally Gets To Orbit The Challenger disaster is one of those things that’s etched into people’s memories. The launch and resulting explosion were broadcast live. Professional astronauts may have been prepared to accept their fate, but that doesn’t make it any less tragic. There’ve been fitting tributes over the years, with people paying homage to the crew members who lost their lives. But a new tribute is remarkable for its simplicity. And this new tribute is all centred around a soccer ball. Ellison Onizuka was one of the Challenger seven who perished on January 28, 1986, when theRead More →
