For Christmas I was given a green 200 mW laser! A couple of AAA batteries later and the laser can point out any star or object in the night sky, with the beam clearly visible the entire way up to infinity. Its the epitome of an Astronomer’s toolkit, at least in my eyes, and it got me thinking about all the amazing things you can see in the sky right now. It also makes me feel like I’m brandishing a light saber, and sadly it’s about as close as I’ll ever get. First off, Venus is back in the evening...
Saturday Morning, 4:47am, Launch: Confirmed. SpaceX launched another successful resupply mission to the International Space Station this morning. The successful launch comes in the wake of the Orbital Sciences Antares rocket explosion back in late October, and is the fourth mission as part of a 12+ Mission contract with NASA worth 1.6 Billion dollars. The Dragon capsule is expected to rendezvous with the ISS early Monday morning, where Astronauts will use the Canada arm to grab it and connect. The capsule will remain connected to the ISS for more than four weeks as ISS astronauts unpack supplies and repack completed experiments...
The Hubble Space Telescope’s just had its 25th Anniversary of bringing us the greatest Astronomical images the world has ever seen. To celebrate, the Hubble team revisited one of Hubble’s most iconic images by pointing the cameras at the Eagle nebula once more. The image, dubbed the ‘Pillars of Creation’ show columns of star forming gas and dust, where the proverbial ‘magic’ happens. But let’s begin with the old image, taken in 1995, so we can compare the differences between then and now. And now the newest image. Quite a striking difference. Like a fine wine, Hubble has only gotten...
NASA is sure to start selling trips to these fabulous space destinations! The only problem is that we have no way of getting there, or more importantly, back home. Still the posters give a great homage to the ‘see America’ posters of the 1920s, and they sure make me want to visit. Kepler 186f is a habitable zone planet around a red dwarf star, meaning it could support liquid water. If any plant life forms on this planet, it would photosynthesize differently, potentially giving it a red colour palette. HD 403007g is a planet with 8 times the mass of Earth....
You may know that the Universe is much more complex than we know. If you look at nearly anything in a different wavelength of light, new details can pop up that you’d never expect. Astronomers today use all the wavelengths of light to study the Universe. Even the most seemingly boring objects can come to life in different wavelengths. As a prime example, take the Moon. Now I don’t find the Moon boring at all, in fact it’s quite interesting and has a lot of influence on the Earth, so its fun to talk about. But when we look at...
Hey, it matters to us humans! A new year, a new start, new goals, dreams, desires, and most of all, hope. Hope that the year ahead will be as good as or better than the one before. The new year is pretty astronomically insignificant though. The Sun orbits the Earth in 365.25 days. We’re just in a different place in space!
I really need to start doing this some day. As you watch the night time movements, remember that the stars are not moving, but the Earth is in fact turning with the camera (and all of us) on it. Feel the motion of the Earth. Also there’s a mind-shredding guitar solo near the end. And have a safe and Happy New Year’s Eve!
From our Sun to Planets to Galaxies and the deep Universe, the top space photos of the year are truly jaw-dropping. Check it out here! Pretty busy this holiday season – will be back to full length posts soon!
The New York Times has come out with some amazing Space features lately, and the latest one is the best visualization of exoplanets I’ve seen. With the Kepler mission’s discovery of nearly 3000 candidate planets, it’s a lot of work to put each system on paper, or digital paper for that matter. Check it out here. Enjoy some exoplanet surfing, from the comfort of your own home.
Yesterday I wrote about young stars that had a habitable zone further away than we thought, and how this would help us spot habitable planets more easily in the future. Today is the second news story this week dealing with finding planets, and it deals with more familiar Sun-like stars and their dusty planetary discs. Dust is both a good thing and a bad thing when looking for planets orbiting other stars. Dust tells us that there is a high likelihood of finding planets, but too much dust blocks out the planets that we look for. Warm dust is worse...
