The Butterfly nebula, an example of a star forming region in the Tarantula nebula. The white scale bar is 2 light years or about 120,000…
‘Galactic archaeology’ refers to the study of second generation stars to learn about the physical characteristics of the first stars, which disappeared only tens of…
Stars identified in the research have formed “shell structures” in the aftermath of a radial merger occurring 3-billion years ago. Credit: Rensselaer Polytechnic Institute Evidence…
Betelgeuse illustration. Credit: NASA, ESA, and E. Wheatley (STScI) It may be another 100,000 years until the giant red star Betelgeuse dies in a fiery…
WPI mathematical physicist Mayer Humi has been studying the solar system for decades. Credit: Worcester Polytechnic Institute/Matthew Burgos Using a limited set of mathematical equations,…
An IRAC infrared image of a filament of young star-forming cores, with the intensity of the dense gas emission overlaid in contours. New submillimeter observations…
This image gallery of stellar winds around cool ageing stars shows a variety of morphologies, including disks, cones, and spirals. The blue colour represents material…
For the first time, an intact, Jupiter-sized, exoplanet has been discovered orbiting close to a white dwarf star. Credit: International Gemini Observatory/NOIRLab/NSF/AURA/J. Pollard For the…
This artist’s conception portrays two neutron stars at the moment of collision. Credit: Dana Berry, SkyWorks Digital, Inc. Colliding neutron stars were touted as the…
Matter from the surrounding protoplanetary disk, the birthplace of planets, is channeled onto the stellar surface by magnetic fields shocking the surface at supersonic velocity.…

A mystery surrounding the space around our solar system is unfolding thanks to evidence of supernovae found in deep-sea sediments. Professor Anton Wallner, a nuclear…
The star-forming nebula W51 is one of the largest “star factories” in the Milky Way galaxy. Interstellar dust blocks the visible light emitted by the…

New observations by the NASA/ESA Hubble Space Telescope suggest that the unexpected dimming of the supergiant star Betelgeuse was most likely caused by an immense…
Artist’s impression of one of this study’s superlative discoveries, the oldest known wide-separation white dwarf plus cold brown dwarf pair. The small white orb represents…
White dwarfs are among the most ancient stellar objects, so their temperatures and predictable lifecycles enable them to work as “cosmic clocks” that can help…
An image from the Heliospheric Imager aboard NASA’s STEREO spacecraft shows the star Betelgeuse, circled. For several weeks in 2020, STEREO was the only observatory…
