Is Betelgeuse about to go supernova?

Astronomers have noted that the star Betelgeuse is becoming less bright, appearing especially faint in the night sky. The dimming represents the biggest dip in brightness of a star yet recorded. Is this the beginning of the end?

Weekend stargazer wins supernova 'cosmic lottery'

Paris - To say that Victor Buso was in the right place at the right time may be the biggest understatement in the history of stargazing.

Scientists are peering millions of years back in time

Thirty years ago, an exploding star 168,000 light years away appeared as a small pinpoint of light in the night sky. The supernova, known as SN 1987A, occurred in a neighboring galaxy called the Large Magellanic Cloud.

A supernova just discovered is the brightest in recorded history

Astronomers have been calling the ASASSN-15lh supernova the brightest in history. The supernova is the largest explosion ever recorded in Space.

We may have overestimated the expansion rate of the universe

New observations of supernovae have suggested that the universe may be expanding much slowly than has been thought up until now. This is a large change that could influence future theories about the end of the universe.

Universe on edge of collapse, at least on cosmological time scale

Astronomers believe the universe is on the edge of "imminent" detruction, at least when viewed on a cosmological time scale.

Astronomers see same supernova several times with Hubble

One hundred years ago, astronomy was a small field, limited by the number of observations scientists made while peering through a telescope.

Clues to supernovae found — right here on Earth

Canberra - Think of supernovae and cosmological events millions of light-years away spring to mind. But a team of scientists contends clues to gaining a better understanding of supernovae lie right beneath our feet, or more precisely, beneath Earth’s oceans.

Review: New on DVD for January 13 Special

This week’s releases include the end of an era on HBO; a start-ups worst nightmare; a meatier but familiar narrative; an excellent Kiwi horror comedy; a sweet love story; and every girl’s best friends from the ‘80s.

Hubble telescope photos reveal presence of 'zombie stars'

Scientists examining images recorded by NASA's Hubble telescope have discovered evidence of "zombie stars,' a star created by a little known form of supernova.

NASA discovers Milky Way's youngest black hole

Scientists with NASA's Chandra X-ray Observatory have discovered what is believed to be the newest black hole to have formed in the Milky Way galaxy.

NASA publishes image of oldest recorded supernova RCW 86

Washington - NASA revealed an image of the oldest recorded supernova on record. The image, which combines data from four telescopes, shows RCW 86, which is approximately 8,000 light-years away and is 85 light-years in diameter.

Canadian girl, 10, youngest ever to discover supernova

A young 10-year-old girl from Fredericton, New Brunswick in Canada is now the youngest person to have discovered a supernova. Kathryn Aurora Gray made the discovery with her father on January 2, 2011.

Supernova 'fireballs' discovered after thousands of years

Two remnants of a supernova have been observed at the Japan/United States Suzaku observatory, and discovered to have contained temperatures 10,000 times hotter than the surface of the sun.

Scientists witness birth of black hole for first time

Astronomers, for the first time, believe they have witnessed the birth of a black hole. The black hole is believed to be a remnant of a supernova, 50 million light years from Earth, which was spotted by an amateur astronomer in 1979.

NASA Announces Newest Supernova Found

NASA has just announced this morning finding the youngest supernova known. At only 140 years of age it is just a youngster by all galactic standards.

New research shows that some old stars known as white dwarfs might be held up by their rapid spins, and when they slow down, they explode as Type Ia supernovae. Thousands of these "time bombs" could be scattered throughout our Galaxy. In this artist's conception, a supernova explosion is about to obliterate an orbiting Saturn-like planet.
