Dark Matter; Dark Energy; We basically use the term ‘dark’ as a cool sounding version of ‘We have no clue what this is.’ But Dark Matter is a better name than ‘We haven’t a clue’ Matter. Over the years, Astronomers have been trying to pinpoint what the stuff actually is that seems to permeate the universe and makes up 26.8% of the entire total energy-mass (Compare this to a paltry 4.9% of ordinary matter, ie the stuff we can see). But now, as per usual, theorists have come up with another possibility for the source of dark matter: moderately sized,...
If you’re in Astronomy circles you may have heard about a big cloud of Hydrogen heading toward the supermassive black hole in the centre of our galaxy, Sagittarius A*. The lead up to the cloud approaching the black hole had astronomers buzzing this year, as it would be a direct opportunity for us to see the black hole ‘devour’ the cloud. The black hole would show us some celestial fireworks and give us a huge opportunity to study their behaviour. Astronomers watched closely, and then the cloud passed right by…. We should have seen the cloud torn apart as matter spiralled...
It’s been a rough week in the space flight industry. On Friday afternoon, a test flight of Virgin Galactic’s SpaceShipTwo class VSS Enterprise resulted in a catastrophe, crashing down in the Mojave desert, killing one pilot, with the other ejecting and now being treated in hospital. During the test flight, launched by Virgin Galactic’s partner corporation Scaled Composites from the Mojave Spaceport, WhiteKnightTwo, an aircraft designed to bring SpaceShipTwo to launch altitude, successfully released the spacecraft. After two minutes, something went wrong, resulting in the eventual crash of the craft. Virgin Galactic released a statement shortly after the accident, saying the National...
If you weren’t aware, new countries have entered the next space race. India’s Mars Orbiter Mission (MOM) named ‘Mangalyaan’ was successfully launched on November 1st, 2013, and has been orbiting Mars since its arrival on September 21st of this year. China has been in the mix since 2007, and have been working to gradually increase their capabilities. Their latest mission, called ‘Chang’e 5-T1,’ was launched on October 23rd, and spent 8 days travelling to the Moon, performing a flyby, and returning safely. This is the test mission before they send Chang’e 5 in 2017, a mission that will land on the...
I did a short presentation last night for a group of families at a Halloween event. My job was to talk space but make it as spooky as possible and use some Halloween themes for the kids. There really is a fine line between teaching Science and being entertaining, but here’s some of the things I did. Lets start with the following image….What does this look like to you? Did you say the head of a witch? Then yes you are right! This is known as the Witch Head Nebula. A nebula is a place where gas and dust in...
The sun is definitely hitting its usual ‘rebellious’ phase on its 11 year sunspot cycle, where it flares up at literally everything. The biggest sunspot observed in 24 years has been releasing huge amounts of energy, in the form of X-class solar flares. In the past week this sunspot, designated AR 12192, has released 3 X-class flares, including a huge X-3.1 on Friday. NASA’s Solar Dynamics Observatory (SDO) has been watching the light show. Okay so the Sun is blowing up, what does all this mean? Let’s start with Sunspots. A sunspot is a place on the sun where there...
Yesterday’s post had me discuss the partial Solar Eclipse that occurred around sunset for most of North America. The one thing I neglected to mention was regarding safe viewing of it. In reality if you saw the sun with your bare eyes during a partial eclipse, it looks like the sun any other time of day – its bright. Don’t damage your eyes. I found a bit of time in the afternoon to build a pinhole camera, which basically consists of a tube or box with a pinhole in one end and a film or ‘viewing area’ at the other...
When comets breakup it can be an emotional time for Astronomers, amateur and professional alike. Though not like a breakup with a significant other, we get our hopes up that the next comet will be a comet of the century. We do this because comets are very unpredictable, and any given close approach to Earth could be spectacular….or terrible. Comet ISON is about to pass behind the sun on November 28th, and could potentially break into pieces from the sun’s incredible tidal forces. In honour of a new potential breakup, here are the top 5 comet breakups in history: #5...
A Commander Chris Hadfield returns home tonight, the York Universe crew will be focusing on his voyage with a special show, featuring talk of the incredible and inspiring exploits of the first Canadian commander of the International Space Station. Featured in this episode will be an interview with one of the newest Canadian Astronauts, Jeremy Hansen. I was lucky enough to be a part of this interview, and am excited that it will finally reach air time tonight! Also debuting tonight after the York Universe episode, will be my second ‘What’s The Latest?’ podcast, entitled ‘Supernova part 1.’ Find it in...
The Hershel Observatory, an ESA telescope for which NASA helped build instruments and process data, has stopped making observations as it has finally run out of its liquid Helium coolant, as expected. This is a good time to remember the multitude of data that a space based telescope can churn out, and the incredible scientific advancement that comes from such missions. On the heels of the NASA proposed budget, it reminds us how important scientific funding and advancement are, especially for countries that have a good standard of living. The high end technology that comes from developing missions like this...
