Leaving so soon? Unusual planetary nebula fades mere decades after it arrived
The tiny Stingray Nebula unexpectedly appeared in the 1980s is by far the youngest planetary nebula in our sky. But a team of astronomers recently analyzed a more recent image of the nebula, taken in 2016 by Hubble, and found that it has faded significantly and changed shape over the course of just 20 years. If dimming continues at current rates, in 20 or 30 years the Stingray Nebula will be barely perceptible. (2020-12-03)

Hubble captures fading of the stingray nebula
Astronomers have caught a rare glimpse of a rapidly fading shroud of gas around an aging star. Archival data from the NASA/ESA Hubble Space Telescope reveal that the nebula Hen 3-1357, nicknamed the Stingray nebula, has faded precipitously over just the past two decades. Witnessing such a swift rate of change in a planetary nebula is exceedingly without precedent, researchers say. (2020-12-03)

In the mysterious Blue Ring Nebula, scientists see the fate of binary stars
Scientists have discovered a rare object called the Blue Ring Nebula, a ring of hydrogen gas with a star at its center. The properties of this system suggest it is the remnant of two stars meeting their ultimate demise: an inward orbital dance that resulted in the two stars merging. The result offers a new window into the fate of many tightly orbiting binary star systems. (2020-11-18)

16-year-old cosmic mystery solved, revealing stellar missing link

ALMA spots metamorphosing aged star
An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has captured the very moment when an old star first starts to alter its environment. The star has ejected high-speed bipolar gas jets which are now colliding with the surrounding material; the age of the observed jet is estimated to be less than 60 years. These features help scientists understand how the complex shapes of planetary nebulae are formed. (2020-03-05)

Journey to the center of Mars
While InSight's seismometer has been patiently waiting for the next big marsquake to illuminate its interior and define its crust-mantle-core structure, two scientists, have built a new compositional model for Mars. They used rocks from Mars and measurements from orbiting satellites to predict the depth to its core-mantle boundary, some 1,800 km beneath the surface and have been able to suggest that its core contains moderate amounts of sulfur, oxygen and hydrogen as light elements.

ALMA catches beautiful outcome of stellar fight
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, have spotted a peculiar gas cloud that resulted from a confrontation between two stars.

But a new analysis reveals evidence of presolar grains in part of a meteorite where they are not expected to be found. (2020-01-28)

Astrophysicists link brightening of pulsar wind nebula to pulsar spin-down rate transition
Astrophysicists have discovered that the pulsar wind nebula (PWN) surrounding the famous pulsar B0540-69 brightened gradually after the pulsar experienced a sudden spin-down rate transition (SRT). This discovery, made by a group of astrophysicists led by GE Mingyu and LU Fangjun at the Institute of High Energy Physics of the Chinese Academy of Sciences, provides important clues to the spin-down mechanism and the magnetic field structure of the pulsar, as well as the physical properties of the PWN. (2019-08-26)

Stellar waltz with dramatic ending
Astronomers at the University of Bonn and their colleagues from Moscow have identified an unusual celestial object. It is most likely the product of the fusion of two stars that died a long time ago. After billions of years circling around each other these so-called white dwarfs merged and rose from the dead. In the near future, their lives could finally end -- with a huge bang. The findings are now presented in Nature. (2019-05-21)

Astronomers discover 2,000-year-old remnant of a nova
For the first time, a European research team involving the University of Göttingen has discovered the remains of a nova in a galactic globular cluster. A nova is an explosion of hydrogen on the surface of a star which makes it much brighter. The remains have formed a glowing nebula. The remnant is located near the centre of the globular cluster Messier 22 and has recently been observed using modern instruments. The results will be published in the journal Astronomy & Astrophysics. (2019-04-29)
