‘ALIEN’ signal solved? Discovery could ‘BREAK THE GATES of discovery’ in the universe

Since 2007, telescopes have continuously picked up a strange, sporadic signal which originates from three billion lightyears away. The strange and rare signals are what as known as ‘fast radio bursts’ or FRBs but scientists are still unsure what causes them. However, what they do know is that they can emit as much energy in a second than the sun does in 10,000 years. They are exceptionally difficult to study as they can last as little as a millisecond and there is no way to predict when they are coming.…

‘Supermassive’ black hole lets out ‘TWO BURPS’ in space binge that moves like ’shockwaves’

The Hubble and Chandra space telescopes detected the burp 800million light-years away. Julie Comerford, from the University of Colorado, said: “Black holes are voracious eaters, but it turns out they don’t have very good table manners. “There are a lot of examples of black holes with single burps emanating out, but we discovered a galaxy with a supermassive black hole that has not one but two burps.” Ms Comerford announced the discovery at the 231st American Astronomical Society meeting in Washington DC. The expert added that “black holes are voracious…

Astronomers just caught a massive black hole ‘burping’ out hot gas not once, but twice

We’ve all felt the pressure that builds up in our stomach after a can of carbonated cola or a particularly filling meal, and no matter how polite of a person you are, you no doubt let a nice healthy burp fly every now and then. As it turns out, black holes have a similar habit, and astronomers have just captured photo evidence of one of the universe’s most destructive entities burping not once, but twice in quick succession. Scientists using some of mankind’s most powerful space observation tools — the…

Black hole spin cranks-up radio volume

Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves. By analyzing nearly 8000 quasars from the Sloan Digital Sky Survey, research team found that the oxygen emissions are 1.5 times stronger in radio loud quasars than in radio quiet quasars. This implies that spin is an important factor in the generation of jets.

NASA renames Swift mission after astronomer Neil Gehrels

NATIONAL HARBOR, Md. — NASA announced Jan. 10 that it was renaming the Swift astronomy spacecraft after its former principal investigator, who passed away last year. During a presentation at a NASA town hall meeting at the 231st Meeting of the American Astronomical Society here, Thomas Zurbuchen, NASA associate administrator for science, said that Swift would now be known as the Neil Gehrels Swift Observatory. Gehrels, who died in February 2017, had been principal investigator for Swift, a mission launched in 2004. The spacecraft was designed to be able to…

New insights into mysterious, cosmic 'fast radio bursts'

The Arecibo Observatory in Puerto Rico. More Astronomers have edged closer to solving the mystery of distant cosmic radio bursts according to a study Wednesday that offers insights into the blasts which emit more energy in a single millisecond than our sun does all day. International astronomers have spotted a few dozen fast radio bursts (FRBs) — and as many as 10,000 may occur daily — but only one has repeated sporadically, known as FRB 121102, allowing it to be studied. Researchers reported in the journal Nature that it appears…

Scientists are baffled by EXTRATERRESTRIAL radio signals coming from deep space

Researchers are perplexed by repeating bursts of radio waves that currently originate from the same location. The fast radio bursts (FRBs) come from a dense stellar core near an extraordinarily powerful magnetic field like one near a massive black hole, according to a study. Study co-lead author Jason Hessels, an astrophysicist at the University of Amsterdam, said: “It is the only known repeating fast radio burst source.” FRBs last just milliseconds and can give off more energy in a fraction of a second than the sun does in weeks. They…

Massive Stars Far Larger and More Common Than Expected—these 'Cosmic Engines' Could Rewrite Astrophysics

Massive stars many times larger than the sun are even bigger, and far more common, than previously believed. New research published in Science has shown these “cosmic engines” could reach 200 to 300 times the size of the sun—a feat previously believed impossible by many astronomers. Their surprising abundance could rewrite our understanding of the universe itself. 1_4_Tarantula Nebula More 30 Doradus contains many massive stars. Researchers mapping almost 1,000 of these stars found many were larger than expected. LTownsley et al/PSU/STScl/CXC/JPL/NASA Stars that hold more than eight to 10 times the mass…

The universe could be full of more huge stars than we thought

Big stars are not so rare in some spotsNASA By Leah Crane There may be more big stars out there than we thought. A study of part of the Large Magellanic Cloud found significantly more huge stars than we would expect to see, which could mean that there are more supernovae and black holes too. In our galactic neighbourhood, all newborn stars seem to follow the same distribution of masses. There are lots of stars about 15 times the mass of the sun, and exponentially fewer stars with higher masses.…
