A Southwest Research Institute scientist has identified stellar phosphorus as a probable marker in narrowing the search for life in the cosmos. Stars with phosphorus…
Asteroid 4-Vesta is the second-largest body in the asteroid belt. Uranium-lead dating and other analytical methods tell researchers which meteorites come from Vesta and also…
The Murchison Widefield Array radio telescope, a portion of which is pictured here, was used to explore hundreds of times more broadly than any previous…
Artist’s conception of a magnetar — a superdense neutron star with an extremely strong magnetic field. In this illustration, the magnetar is emitting a burst…
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…
Artist’s impression of the explosion and burst of gravitational waves emitted when a pair of superdense neutron stars collide. New observations with radio telescopes show…
Multi-frequency composite VLBA image of the galaxy TXS 0128+554, 500 million light-years from Earth. The image shows young radio jets originating near a supermassive black…
