Scientists watch a black hole shredding a star
A satellite searching space for new planets gave astronomers an unexpected glimpse at a black hole ripping a star to shreds. The milestone was reached with the help of a worldwide network of robotic telescopes headquartered at The Ohio State University called ASAS-SN (All-Sky Automated Survey for Supernovae). Astronomers from the Carnegie Observatories, Ohio State and others will publish their findings Sept. 26 in the Astrophysical Journal. (2019-09-26)

NASA's TESS mission spots its 1st star-shredding black hole
For the first time, NASA's planet-hunting Transiting Exoplanet Survey Satellite (TESS) watched a black hole tear apart a star in a cataclysmic phenomenon called a tidal disruption event. Follow-up observations from other instruments have produced the most detailed look yet at the early moments of one of these star-destroying occurrences. (2019-09-26)

Providing a solution to the worst-ever prediction in physics
The cosmological constant introduced a century ago by Albert Einstein is a thorn in the side of physicists. The difference between the theoretical prediction of this parameter and its measurement is of the order of 10,121. This estimate is considered the worst in the history of physics. A researcher from the University of Geneva, Switzerland, proposes an approach that may resolve this inconsistency by accepting that another constant -- Newton's universal gravitation G -- may vary.

Smash and grab: A heavyweight stellar champion for dying stars
PNe theoretically derive from stars in the range 1-8 times the mass of the Sun, representing 90% of all stars more massive than the sun. However, until now, PNe have been proven to derive from stars born with only 1-3 times the mass of our Sun. HKU researchers have now officially smashed this previous limit and grabbed proof that a PNe has emerged from a star born with 5.5 times the mass of our Sun. (2019-06-24)

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)

Subaru Telescope captures 1800 exploding stars
The Subaru Telescope has captured images of more than 1800 exploding stars in the Universe, some located 8 billion light years from Earth. (2019-05-30)

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)

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.

(2019-05-07)

Secrets of the 'blue supergiant' revealed
'Blue supergiants' -- the final phase in a giant star's lifetime -- have been seen for the fist time. (2019-05-06)

Blue supergiant stars open doors to concert in space
Blue supergiants are rock-and-roll: they live fast and die young. This makes them rare and difficult to study. Before space telescopes were invented, few blue supergiants had been observed, so our knowledge of these stars was limited. Using recent NASA space telescope data, an international team led by KU Leuven studied the sounds originating inside these stars and discovered that almost all blue supergiants shimmer in brightness because of waves on their surface. (2019-05-06)

The 'stuff' of the universe keeps changing
The composition of the universe--the elements that are the building blocks for every bit of matter -- is ever-changing and ever-evolving, thanks to the lives and deaths of stars.

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)

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)

Newly discovered supernova complicates origin story theories
A supernova discovered by an international group of astronomers including Carnegie's Tom Holoien andMaria Drout, and led by University of Hawaii's Ben Shappee, provides an unprecedented look at the first moments of a violent stellar explosion. The light from the explosion's first hours showed an unexpected pattern, which Carnegie's Anthony Piro analyzed to reveal that the genesis of these phenomena is even more mysterious than previously thought. (2018-11-29)
