A massive star's dying breaths
Betelgeuse has been the center of significant media attention lately. The red supergiant is nearing the end of its life, and when a star over 10 times the mass of the Sun dies, it goes out in spectacular fashion. With its brightness recently dipping to the lowest point in the last hundred years, many space enthusiasts are excited that Betelgeuse may soon go supernova, exploding in a dazzling display that could be visible even in daylight.

Revealed: The explosive origin of superluminous supernova SN 2006gy
Providing answers about its curious supreme brightness, researchers say the superluminous supernova SN 2006gy -- one of the brightest stellar explosions ever studied, and discovered in 2006 -- gained its exceptional luster when a normal Type Ia explosion smashed into a surrounding shell of ejected stellar material. (2020-01-23)

New insights about the brightest explosions in the Universe

Explosion or collapse?
A group of scientists, among them several from GSI Helmholtzzentrum für Schwerionenforschung and from Technical University of Darmstadt, succeeded to experimentally determine characteristics of nuclear processes in matter ten million times denser and 25 times hotter than the center of our sun. A result of the measurement is that intermediate-mass stars are very likely to explode, and not, as assumed until now, collapse. The findings are now published in the scientific magazine Physical Review Letters. (2020-01-10)

Stardust from red giants
Some of the Earth's building material was stardust from red giants, researchers from ETH Zurich have established. They can also explain why the Earth contains more of this stardust than the asteroids or the planet Mars, which are farther from the sun. (2019-12-10)

Extremely energetic particles coupled with the violent death of a star for the first time
Researchers at the Niels Bohr Institute, University of Copenhagen and DTU Space have determined the emission of extremely energetic light particles during the death of a very heavy star for the first time, using the telescope MAGIC. The scientific perspective -- the source detection of the emission of particles - is to gain basic insights into the extreme physical processes in the death of the heaviest stars. The study is now published in the journal Nature (2019-11-21)

Outback telescope captures Milky Way center, discovers remnants of dead stars
A radio telescope in the Western Australian outback has captured a spectacular new view of the centre of the galaxy in which we live, the Milky Way. The image from the Murchison Widefield Array (MWA) telescope shows what our galaxy would look like if human eyes could see radio waves. (2019-11-20)

Hubble sets sights on an explosive galaxy
When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae. A supernova event is incredibly energetic and intensely luminous -- so much so that it forms what looks like an especially bright new star that slowly fades away over time. (2019-06-14)

Researchers wonder if ancient supernovae prompted human ancestors to walk upright
Supernovae bombarded Earth with cosmic energy starting as many as 8 million years ago, with a peak some 2.6 million years ago, initiating an avalanche of electrons in the lower atmosphere and setting off a chain of events that feasibly ended with bipedal hominins. (2019-05-28)

Explosions of universe's first stars spewed powerful jets
Instead of ballooning into spheres, as once thought, early supernovae ejected jets that may have seeded new stars. (2019-05-08)

Could this rare supernova resolve a longstanding origin debate?
Detection of a supernova with an unusual chemical signature may hold the key to solving the longstanding mystery that is the source of these violent explosions.

Giant 'megalodon' shark extinct earlier than previously thought
'Megalodon' -- a giant predatory shark that has inspired numerous documentaries, books and blockbuster movies -- likely went extinct at least one million years earlier than previously thought, according to new research published Feb. 13 in PeerJ. This is a substantial adjustment as it means that O. megalodon likely went extinct long before a suite of strange seals, walruses, sea cows, porpoises, dolphins and whales all disappeared sometime about 1-2.5 million years ago. (2019-02-13)

Do you like Earth's solid surface and life-inclined climate? Thank your lucky (massive) star

Observations of a rare hypernova complete the picture of the death of the massive stars
The end of a star's life can occur in a tranquil manner in the case of low mass stars. This is not the case for very massive stars, which suffer such extreme explosive events that they can outshine the brightness of the whole galaxy. A group of astronomers has published a study of the death of a high-mass star that produced a gamma-ray burst (GRB) and a hypernova, in which they have detected a new component in this type of events. (2019-01-16)

Astronomers find signatures of a 'messy' star that made its companion go supernova
On Jan. 10 at the 2019 American Astronomical Society meeting in Seattle, an international team of astronomers announced that they have identified the type of companion star that made its partner in a binary system, a carbon-oxygen white dwarf star, explode. Through repeated observations of SN 2015cp, a supernova 545 million light years away, the team detected hydrogen-rich debris that the companion star had shed prior to the explosion. (2019-01-10)

Birth of a black hole or neutron star captured for first time
After combining several imaging sources, including hard X-rays and radiowaves, a Northwestern University-led team now speculates that the telescopes captured the exact moment a star collapsed to form a compact object, such as a black hole or neutron star. The stellar debris, approaching and swirling around the object's event horizon, caused The Cow's remarkably bright glow. (2019-01-10)

Unusual supernova opens a rare window on the collapse of a star
An unusual supernova studied by multiple telescopes, including the SOAR telescope and other telescopes at the National Science Foundation's (NSF) Cerro Tololo Inter-American Observatory (CTIO) and NSF's Kitt Peak National Observatory (KPNO), is thought to herald the birth of a new black hole or neutron star, caught at the exact moment of its creation. Observations made with facilities ranging from X-rays to optical and radio wavelengths were used to understand this remarkable event. (2019-01-10)

First evidence of gigantic remains from star explosions
Astrophysicists have found the first ever evidence of gigantic remains being formed from repeated explosions on the surface of a dead star in the Andromeda Galaxy, 2.5 million light years from Earth. The remains or 'super-remnant' measures almost 400 light years across. The super-remnant -- larger than almost all known remnants of supernova explosions -- is consistent with being built up by frequent nova eruptions over millions of years. (2019-01-09)

Calibrating cosmic mile markers
New work from the Carnegie Supernova Project provides the best-yet calibrations for using type Ia supernovae to measure cosmic distances, which has implications for our understanding of how fast the universe is expanding and the role dark energy may play in driving this process. The research was led by Carnegie astronomer Chris Burns. (2018-12-11)
