GRB 130427A: Brightest Ever Gamma-Ray Burst Detected

November 21, 2013 Comments off

An unusual stellar explosion observed on April 27, 2013 by NASA’s Swift satellite is the brightest gamma-ray burst (GRB) ever recorded, says a multinational team of astronomers.

The event, labeled GRB 130427A, produced a jet of matter moving close to the speed of light, which was formed when a massive star collapsed to make a black hole at its center. As a result, a blast wave caused the rest of the star to expand outwards, producing a glowing shell of debris observed as an extremely bright supernova.

GRB 130427A happened in a galaxy a quarter of the way across the Universe. Although far away, this is much closer than a typical GRB allowing astronomers to confirm for the first time that the same object can simultaneously create both a powerful GRB and a supernovae.

“We normally detect GRBs at great distance, meaning they usually appear quite faint. In this case the burst happened only a quarter of the way across the Universe meaning it was very bright. On this occasion, a powerful supernova was also produced, something we have not recorded before alongside a Read more…

Risk of asteroid hitting Earth is ten times higher than we thought

November 7, 2013 Comments off

This is frightening. Nature just published a study by astronomers who have reanalyzed and recalculated the estimate of asteroids that could hit Earth and it’s a lot worse than we thought. Ten times worse.

As in, researchers are now saying we are 10 times more likely to get struck by an asteroid than before. As in, scientists are saying we need to improve our early warning systems. As in, yikes.

Here’s the thing. Researchers have always had a fairly decent track record in spotting humungous asteroids that might hit Earth. That’s because NASA previously only looked for space rock 100 feet wide and bigger. But in the aftermath of the meteorite that exploded over Russia, they’re beginning to realize that smaller asteroids are still insanely powerful and damaging and desperately need to be kept track of too.

For example, the meteorite in Russia was only 62 feet wide but still exploded over Read more…

Astronomers find the oldest known star in the universe

August 12, 2013 Comments off

A Digitized Sky Survey image of the Methuselah Star, the oldest known star in our galaxy.Scientists have discovered Methuselah, what is being called and “impossible star,” which appears to be potentially older than the universe.
The Milky Way’s own Methuselah star, formerly knows as HD 140283, seems to be between 14 to 16 billion years old, which is providing a bit of a continuity error in science, since most researches believe the universe to be 13.8 billion years old. However, a team of scientists have worked to try and come up with an explanation for the paradoxical star, accounting several factors such as its distance from us, its brightness and its structure. These scientists have been able to place the star back to approximately 14.5 billion years— still making it older than the universe. But with a margin of error of 800 million years, this can put the star at 13.7 billion years old, possibly making it younger than the universe (but just barely). Discovered over a century ago, the ancient star was found to be moving more than an astonishing 800,000 mph (1.3 million km/h) relative to our own galaxy. Originally born in a dwarf galaxy, which the Milky Way “ate” 12 billion years ago. Now the star, which has become more of a red giant, is a distant 190.1 light-years away in the Libra constellation and continues a long orbit around our galaxy.

 

Asteroid 2013 PS13 Closest Approach Today and will Fly Between the Earth and the Moon at a Distance of 203.700 km (0,5 LD) – It was Discovered on August 7 !!!!

In comparison, the size of the meteorite that fell earlier this year in Russia was about 18 m as this was the 2nd undiscovered near earth asteroid this week!

As reported Astronomical Union and the University of Madrid, the newly discovered asteroid 2013 PS13 today will fly between the Earth and the Moon at a distance of 203.700 kilometers from Earth.

The Minor Planet Center of the International Astronomical Union reported, that the newly found asteroid was discovered at August 7 by the Spanish La Sagra Observatory in the province of Granada.
 Carlos de la Fuente Marcos said, that the asteroid 2013 PS13 has a size of up to 19 meters, it will fly at a Read more…

Hubble sees the fireball from a kilonova

August 7, 2013 Comments off

NASA’s Hubble Space Telescope has detected a new kind of stellar blast called a kilonova that’s about 1,000 times brighter than a regular nova.

A kilonova happens when a pair of compact objects such as neutron stars crash together. Hubble observed the fading fireball from a kilonova last month, following a short gamma ray burst (GRB) in a galaxy almost 4 billion light-years from Earth.

In the image at left, the galaxy in the center produced the gamma-ray burst, designated GRB 130603B. The galaxy resides almost 4 billion light-years away. A probe of the galaxy with Hubble’s Wide Field Camera 3 on June 13, 2013, revealed a glow in near-infrared light at the source of the gamma-ray burst, shown in the Read more…

Comet Pan-STARRS will grace northern skies this week

Comet Pan-STARRS, which is currently dazzling the night skies in the southern hemisphere, will reach its closest approach to the Earth today, and within the next few days, it will climb above the western horizon for those living in the northern hemisphere.

Comet C/2011 L4 (Pan-STARRS) was discovered in June 2011 using the University of Hawaii’s Panoramic Survey Telescope & Rapid Response System (Pan-STARRS). Astronomers initially predicted that it would be a very bright comet, but up until last week, it was falling well short of expectations. However, as Pan-STARRS flew past the orbit of Mercury, it brightened significantly, finally living up to the astronomer’s hopes.
