B612 says Earth avoids massive asteroids with “blind luck”

B612 says Earth avoids massive asteroids with “blind luck”

With Earth Day round the bend, you’d expect to hear some positive news regarding our planet and the celestial bodies that surround it; instead we have some not-so-good-news. According to former NASA astronauts, we're depending on "blind luck" when it comes to the asteroids avoiding our planet. Apparently we get hit three to ten times more by large-scale asteroids than what is being officially declared by the authorities, this information being brought forward by this trio of space-fairing fellows this week.

Astral Beauty: Gravitational microlensing spots first Exomoon

Astral Beauty: Gravitational microlensing spots first Exomoon

Astronomers have caught a glimpse of an exomoon for the first time, with a rare space line-up allowing complex telescope tech to catch a never-to-be-repeated sighting. Astral bodies like planets and moons lying outside our Solar System are referred to as exoplanets and exomoons. Scientists use a technique called gravitational microlensing to view these bodies, with the trick to observing them accurately being picking a time when all the stars are aligned in space.

Real-life “Death Stars” deadlier than Darth Vader astronomers find

Real-life “Death Stars” deadlier than Darth Vader astronomers find

Alderaan isn't the only planet to fall victim to the "Death Star", astronomers claim, though the vast O-type stars actually across the galaxy destroying young planets before they've had time to form don't have convenient exhaust ports to stop them. Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team of US and Canadian researchers discovered that huge quantities of ultraviolet radiation from stars at least 16-times the mass of our own sun can blast away the raw materials for new planetary systems.

Erratic exoplanet Kepler-413b has a wobbly orbit

Erratic exoplanet Kepler-413b has a wobbly orbit

Scientist and astronomers are discovering a large number of new planets using the Kepler Space Telescope. One of the latest planets discovered by the space telescope is called Kepler-413b. The planet is rather baffling to scientists because it has a wildly erratic orbit making the planet very wobbly.

Forensic Astronomy determines exact date and time Monet painted “Sunset” masterpiece

Monet was one of the most famous artiest to ever put brush to canvas. His body of work has some of the most identifiable pieces of art ever created and over the years more than a few people have looked at his art and wondered exactly when and where the artist captured the landscapes he is famous for. One of these landscape masterpieces is called "Sunset."

Gaia satellite launches, will chart 1 billion stars 70 times over 5 years

Gaia satellite launches, will chart 1 billion stars 70 times over 5 years

The European Space Agency last week launched Gaia, a star-charting satellite that will repeatedly survey a billion stars over the course of five years. It is en route to a virtual orbit point called "L2", 1.5 million km further from the sun than the planet Earth orbits. It will measure the position, brightness, temperature and chemical composition of each star 70 times.

China’s Chang’e-3 lander and Jade Rabbit rover land on moon

China's "Long March to the Moon" has placed a lander and a rover on the moon. The Chang'e-3 lander and her accompanying Yutu or "Jade Rabbit" rover arrived inside the right eye of the "Man in the Moon" this evening at 9:00PM Beijing time. This marks the first time in more than 40 years anyone has performed a soft lunar landing. All sources point to a successful deployment for the robot visitors.

Comet ISON declared dead by scientists

Comet ISON declared dead by scientists

Astronomers and sky watchers around the world watched in anticipation in late November and early December as comet ISON made its close pass around the sun. The prediction was that if the comet survived its close encounter with the sun, it would be one of the brightest comets in centuries. Sadly, when the comet went behind the sun, it didn’t emerge as hoped.
