Sources of Gravitational Waves: The Most Violent Events in the Universe

Soon, very soon, Thursday, February 11, at 10:30 Eastern time, we are likely to learn at any one of several press conferences — at the National Press Club in Washington, D. C., in Hannover, Germany, near Pisa in Italy and elswhere — that gravitational waves have been measured directly, for the first time. This would mean the first direct detection of minute distortions of spacetime, travelling at the speed of light, first postulated by Albert Einstein almost exactly 100 years ago. Time t...

the gravity of new life

the rumour is that the LIGO project has detected a significant signal of gravitational waves originating from two distant black holes orbiting each other and merging together! a big press release from the Laser Interferometer Gravitational-wave Observatory (LIGO) is scheduled for tomorrow (Thursday, Feb. 11, 2016 10:30 AM US EST). you can WATCH the news of the project update HERE. so what are gravitational waves? PhD Comics explains them very well in this video:and if you're curio

Astro Update!

Well, we finally got some clear skies over the past week, and I have been able to get out and observe. The conditions have been great, with a little wind that has added to the chill factor during these so-called winter months (temps have been a lot higher than normal this year). It had been a while since I have actually imaged, so I got out under the stars a couple of times and revisited some old friends. Below are a couple of shots of the Sword of Orion region, with different processing workflow

Gravitational Wave Detectors: How They Work

It's official: this Thursday, February 11, at 10:30 EST, there will be parallel press conferences at the National Press Club in Washington, D. C., in Hannover, Germany, and near Pisa in Italy. Not officially confirmed, but highly probable, is that people running the LIGO gravitational wave detectors will announce the first direct detection of a gravitational wave. The first direct detection of minute distortions of spacetime, travelling at the speed of light, first postulated by Albert Einstein a

Vesta Rules the February Dusk Skies

Missing out on the morning planetary action?February sees all five naked eye planets in the dawn sky, though that's about to change in March. But the good news is, now is the time to hunt for a sometimes planet, sometimes asteroid in the early evening. We're talking about 4 Vesta. The 4th┬identified resident of the asteroid belt, discovered by Heinrich Olbers in 1807, Vesta made its way into many planetary listings in the 19th century before its demotion to asteroid. It then enjoyed a very brief

New Horizons Latest Find: Floating Ice Hills On Pluto!

Ever since the New Horizons spacecraft flew by Pluto in July 2015, people here at Earth have been treated to an endless supply of discoveries about the dwarf planet. These included the first accurate pictures of what Pluto looks like, images of "Pluto's Heart", information about the geology and morphology of the surface (and its largest moon, Charon), and information about Pluto's atmosphere and its escape rate. And based on the data obtained from images by the New Horizons probe, NASA recently a

Peculiar Cauliflower Rocks' May Hold Clues To Ancient Mars Life

Evidence of water and a warmer, wetter climate abound on Mars, but did life ever put its stamp on the Red Planet? Rocks may hold the secret. Knobby protuberances of rock┬discovered by the Spirit Rover in 2008 near the rock outcrop Home Plate in Gusev Crater caught the attention of scientists back on Earth. They look like┬cauliflower or coral, but were these strange Martian rocks sculpted by microbes, wind or some other process?When analyzed by Spirit's mini-TES (Mini-Thermal Emission Spectrome

NASA Says No Chance Small Asteroid Will Hit Earth On March 5th

On October 6th, 2013, the Catalina Sky Survey discovered a small asteroid which was later designated as 2013 TX68. As part Apollo group this 30 meter (100 ft) rock is one of many Near-Earth Objects (NEOs) that periodically crosses Earth's orbit and passes close to our planet. A few years ago, it did just that, flying by our planet at a safe distance of about 2 million km (1. 3 million miles). And according to NASA's Center for NEO Studies (CNEOS) at the Jet Propulsion Laboratory, it will be passin

A Challenge in Visual Athletics: Hunting the Gegenschein

Looking for something truly elusive? Astronomy has no shortage of the fleeting and ephemeral when it comes to challenges. This week's challenge will require supremely dark skies and persistence. We're talking about the gegenschein, the elusive counter glow lying opposite to the Sun across the plane of the ecliptic. We bring this up now, as the Moon heads towards New phase on February 8th and we still enjoy long nights for northern hemisphere observers prior to the equinox and the return to daylig

Massive Ariane 5 To Launch Giant NextGen Telescope In Dynamic Deployment To L2

The Ariane 5 rocket is a workhorse for delivering satellites and other payloads into orbit, but fitting the James Webb Space Telescope (JWST) inside one is pushing the boundaries of the Ariane 5's capabilities, and advancing our design of┬space observatories at the same time. The Ariane 5 is the most modern design┬in the ESA's┬Ariane rocket series. It's responsible for delivering things like┬Rosetta, the Herschel Space Observatory, and the Planck Observatory into space.

Milky Way with Nearby Constellations by Matt Dieterich

Here's an amazing photograph of the Milky Way by astrophotographer Matt Dieterich. He took the image a step further, however, and identified all the constellations you can see close to the Milky Way. You'll want to click this image and see a bigger version. Right down near the horizon is Sagittarius - it looks like a teapot, with the Milky Way rising like steam from its spout. Many of the brightest, most spectacular nebulae in the night sky are located around this constellation: the Lagoon Nebula,

Lonely But Not Alone: A Planet Orbits its Star at 1 Trillion Kilometres

The Royal Astronomical Society (RSA) has announced the discovery of a planet that orbits its star at a distance of 1 trillion kilometres. This is easily the furthest distance between a star and a planet ever found. For comparison, that's 7,000 times further than the Earth is from the Sun. At that distance, a single orbit takes about 900,000 years, meaning that the planet has orbited its star less than 50 times. The planet itself was discovered in an infrared sky survey by US researchers, and foll

This Road Leads to the Heart of the Milky Way

This road near Phoenix, Arizona leads to the heart of the Milky Way. Well, that's assuming your car will handle the 26,000 light-year drive, and can fly through, uh, space. And you can endure the cold, radiation and space madness. Anyway, you get the metaphor. Tyler Sichelski took this photo of the galactic core, the central bulge of the Milky Way. It's a region of incredible density and activity, and at the very heart, hidden from our view is the Milky Way's supermassive black hole, with 4 milli

Five things we know about the universe that will make you feel very small

Here is an article I contributed to ABC Science, originally posted here. Five things we know about the universe that will make you feel very small. One thing we know about the universe is that it's really big. Another is that thinking about it and trying to understand it will make your brain hurt. Astronomer Amanda Bauer takes us through her top five mind-expanding things we know (or don't know) about the universe. 1. There is no edge of the universePHOTO: Full-sky map of the oldest lig

Why Haven't We Heard From All The Aliens? Because They're All Dead!

In 1950, physicist Enrico Fermi raised a very important question about the Universe and the existence of extra-terrestrial life. Given the size and age of the Universe, he stated, and the statistical probability of life emerging in other solar systems, why is it that humanity has not seen any indications of intelligence life in the cosmos? This query, known as the Fermi Paradox, continues to haunt us to this day. If, indeed, there are billions of star systems in our galaxy, and the conditions nee

Though not a true planetary alignment as extolled by many websites, this is a great chance to see all five classical planets above the horizon at once... or seven, if you count the waning gibbous Moon and the rising Sun, as the ancients did as part of their geocentric, Earth-entered universe.

Astronomers Find Theoretical Evidence for Distant Gas Giant Planet in Our Solar System

The astronomer known worldwide for vigorously promoting the demotion of Pluto from its decades long perch as the 9th Planet, has now found theoretical evidence for a new and very distant gas giant planet lurking way beyond Pluto out to the far reaches of our solar system. In an obvious reference to the planethood controversy, the proposed new planet is nicknamed Planet Nine' and its absolutely huge! The possible planet has a mass about 10 times that of Earth and is believed to be gaseous, li

Lights Out: A Fine Occultation of Aldebaran Spans the Atlantic

They braved the cold, cursed the clouds, wrestled with frozen telescope focusers and more, as dedicated astros worked to catch the first occultation of the bright star Aldebaran┬for 2016 by the waxing gibbous Moon. The event went down last night into the wee hours of the morning, and was visible across North America into western Europe and the United Kingdom. We're always amazed at the sorts of astro-images folks take of a given event, now shared in near real time across social media. Less than a

Watch the Moon Occult Aldebaran Tuesday Night

That's no moon... But in this case, it is (sorry Ben), and that Moon is headed to temporarily obliterate (occult) the view of the bright star Aldebaran as seen from the Earth on the evening of January 19th and into the morning of the 20th. Here are the specifics. Not to be confused with Princess Leia's homeworld of Alderaan of Star Wars science fiction fame, the occultation of the bright star Aldebaran in the astronomical constellation Taurus occurs on the night of Tuesday, January 19th┬and

What Would Earth Look Like With Rings?

Saturn's Rings are amazing to behold. Since they were first observed by Galileo in 1610, they have been the subject of endless scientific interest and popular fascination. Composed of billions of particles of dust and ice, these rings span a distance of about 282,000 km (175,000 miles) - which is three quarters of the distance between the Earth and its Moon - and hold roughly 30 quintillion kilograms (that's 3. 0. x 1018 kg) worth of matter.
