Astronomers using ESO’s Very Large Telescope Interferometer (VLTI) have captured a zoomed-in image of the dust-enshrouded red supergiant star WOH G64. This image, taken by the GRAVITY instrument on ESO’s Very Large Telescope Interferometer, shows the red supergiant WOH G64. Image credit: ESO / Ohnaka et al., doi: 10.1051/0004-6361/202451820. WOH G64 is located approximately 160,000

Astronomers have discovered a transiting exoplanet — named IRAS 04125+2902b — orbiting a 3-million-year-old, 0.7-solar-mass protostar in the Taurus Molecular Cloud. An artistic interpretation of the IRAS 04125+2902 system. Image credit: NASA / JPL-Caltech / R. Hurt & K. Miller, Caltech & IPAC. IRAS 04125+2902b has a radius of 0.96 Jupiter radii and a mass of

Nectar foraging by Ethiopian wolves (Canis simensis) may contribute to the pollination of the Ethiopian red hot poker flower (Kniphofia foliosa), according to a new paper published in the journal Ecology. An Ethiopian wolf (Canis simensis) licks nectar from the Ethiopian red hot poker flower (Kniphofia foliosa). Image credit: Adrien Lesaffre. The Ethiopian wolf —

Astronomers using the Dark Energy Spectroscopic Instrument (DESI), a state-of-the-art instrument mounted on NSF’s Nicholas U. Mayall 4-m telescope at Kitt Peak National Observatory, have mapped how nearly 6 million galaxies cluster across 11 billion years of cosmic history. Their results provide one of the most stringent tests yet of Albert Einstein’s general theory of

The 36,000-year-old frozen specimen from Yakutia belongs to Homotherium latidens , a species of scimitar-toothed cat that inhabited Eurasia during the Pliocene and Pleistocene epochs, and significantly differs from a modern lion cub in the elongated front legs, the unusual shape of the muzzle with a large mouth opening and small ears, the very massive

New research from the University of Birmingham explores the nature of photons — individual particles of light — in unprecedented detail. Ben Yuen & Angela Demetriadou define the precise shape of a single photon.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have captured high-resolution images of eight protoplanetary disks in Sigma Orionis, a star cluster irradiated by intense ultraviolet light from a massive star. To their surprise, they’ve found evidence of gaps and rings in most of the disks — substructures commonly associated with the formation of giant

Paleontologists have described a new species of pachypleurosaur from the Middle Triassic of southwestern China. The holotype of Dianmeisaurus mutaensis from the Guanling Formation, China: (A) the skeleton in dorsal view; (B) the counterpart of (A). Scale bars – 1 cm. Image credit: Hu et al., doi: 10.1186/s13358-023-00292-4. Dianmeisaurus mutaensis lived in what is now
