Jan 10 - Astronomers discover radio signal from galaxy billions of light years away

Canadian astronomers have reportedly discovered a repetitive radio signal some 2.5 billion light-years away from Earth — only the second example known to mankind.

A telescope in British Columbia, otherwise known as Canadian Hydrogen Intensity Mapping Experiment (CHIME), detected 13 pulses — or fast radio bursts (FRBs) — in July and August, according to a Monday report from Nature, a British scientific journal.

The findings were announced by Deborah Good, an astronomer at the University of British Columbia in Vancouver, at a meeting of the American Astronomical Society in Washington on Wednesday.

"Look! We see FRBs," she said of the cosmic flashes, which remain a mystery to astronomers. Before they were spotted over the summer, astronomers reportedly found between 50 and 60 examples of the radio bursts.

Good said that "if we had 1,000 examples, we would be able to say many more things about what FRBs are like."

The CHIME telescope found, as phrased by Nature.com, "the second known FRB that repeats, meaning that the radio flashes re-appear at the same point in the sky." The first FRB that repeats was detected in 2012.

The majority of the FRBs discovered by the telescope showed signs of "scattering," Phys.org reported — which led the CHIME team to believe the radio bursts are "powerful astrophysical objects."

"That could mean in some sort of dense clump like a supernova remnant," Cherry Ng, an astronomer at the University of Toronto, told the news outlet. "Or near the central black hole in a galaxy. But it has to be in some special place to give us all the scattering that we see."

Astronomers' studying of FRBs can teach those who study more about where the bursts come from, and whether that region in its galaxy is home to turbulent gas.

"Until now, there was only one known repeating FRB.," astronomer Ingrid Stairs, also a member of the CHIME team, said. "Knowing that there is another suggests that there could be more out there. And with more repeaters and more sources available for study, we may be able to understand these cosmic puzzles — where they're from and what causes them."

I wonder how fast the source was able to send this signal and how long ago it was sent.

billions of years (with human tech). we can see 35 billion years in the past, so its crazy to think something like a massive explosion happened a million years ago and we're just seeing/hearing it. so who knows what going on in space right now. it takes to long for the info to get to us

Isn’t light years based around distance? Not actually time?

"Billions of light years away"

How long did that signal take to get back to Canada?

Sometimes it's hard to believe this sh*t.

Billions Of Years.?? Possibly, but We can only quantify the amount of time it takes to travel light year here on earth.

The source could be advanced to the point where a billion light years are travelable at a faster speed.

yeah its distance i think 1 light year is 5 trillion miles. the rough conversion based on our neighbor galaxy.

Andromeda is 2,538,000 light years away, and at the speed of light, at which none other than light can travel, it would take 2.54 million years to just get there.

The average human lifespan is 71 years. Therefore, if NASA decided to send a probe to Andromeda, 35,774 generations of humans would have set foot on Earth before the probe even reached Andromeda.

Likewise, is a NASA spacecraft travelling at 17,000 miles per hour was sent towards Andromeda, it would take about 844.7 trillion hours, or 7x the age of the universe, or just about 94.5 billion Earth years. and that our neighboring galaxy.

its so much to discover...these numbers are crazy

this stuff is facisnating to me because it show we're arent sh*t in comparison to the vastness of the cosmos. all that earth drama is meaningless.

2.5 billion light years as stated in the article. It doesn't have to be intentionally sent.

For example.. our radio waves broadcasting a little over a mere 100 years have traveled around 200 light years I think. Not far at all. Milky way is like 100 200 k lightyears. Interesting because that would mean these waves came from outside the galaxy.

I'll look more into this this weekend maybe

There's some issues with that. Light is constant. It's the same speed everywhere in the universe

You’re confusing the “speed of light” and a “Light Year”.

A Light Year is used to measure distance. It’s a term used to quantify how far light can travel in a year.

How fast something or someone travels that distance is relative to the source.

I know that. It doesn't change the fact that light is constant. This is special relativity until proven otherwise. We measure light at this constant speed. How else would we know stellar distances? Ofcourse we utilize light years.. these are great distances in which the 0s are staggering in the absence of such. Go read up on special relativity then come talk to me youngin

186,000 miles per second. Constant everywhere in this universe until we can agree on something better with the appropriate data and rigors of time @
