Astronomer Frank Drake dies

On Friday, September 2, 2022, at the age of 93, American astronomer Frank Drake, who became one of the pioneers of the search for radio signals from extraterrestrial civilizations, died. He is also one of the creators of the records for the Pioneer and Voyager probes and the Arecibo radio message, according to the SETI… Continue reading Astronomer Frank Drake dies

A galaxy merger could extinguish a burst of star formation.

Astronomers have found for the first time an example of the result of the merger of two galaxies, where the merger process itself inhibited the formation of new stars, throwing out most of the cold gas reserves from the galaxies. In the case of SDSS J1448+1010, about 47 percent of the material needed to form… Continue reading A galaxy merger could extinguish a burst of star formation.

The Event Horizon Telescope saw the bend of the distant blazar's jet

The Event Horizon Telescope (EHT) has captured the most detailed image yet of the interior of the relativistic jet blazar J1924-2914, whose light took 3.5 billion years to reach Earth. It turned out that as it moves away from the core, the jet begins to bend, and toroidal magnetic fields can act in the region… Continue reading The Event Horizon Telescope saw the bend of the distant blazar's jet

James Webb captures its most extensive deep sky image yet

As part of the CEERS sky survey, the James Webb Infrared Space Telescope captured its record-breaking wide-angle deep image of a patch of sky in the constellation Ursa Major. It contains a huge number of galaxies that existed at different stages in the life of the Universe, including one of the candidates for a record-distant… Continue reading James Webb captures its most extensive deep sky image yet

Astronomers have found very long radio jets near a nearby active galaxy

Astronomers have discovered two jets of relativistic plasma near the active galaxy NGC 2663, close to the Milky Way, which are characterized by amazing smoothness and enormous length, reaching more than a million light years. For one of them, scientists observed for the first time jet recollimation on a kiloparsec scale, which manifests itself in… Continue reading Astronomers have found very long radio jets near a nearby active galaxy

James Webb saw auroras on Jupiter

The James Webb Infrared Space Telescope has captured new images of the Jupiter system. On them, in addition to details in the planet’s atmosphere and auroras, you can see the rings of Jupiter and a couple of its satellites, according to the NASA website. The Jupiter system, like the gas giant itself, represents important targets… Continue reading James Webb saw auroras on Jupiter

The Gemini telescope reduced the mass of the heaviest known star

Using the ground-based Gemini South telescope, astronomers have obtained a record-breakingly detailed image of the central zone of the R136 cluster, where the heaviest known star, R136a1, is located. Observational data made it possible to clarify the mass of the most massive stars in the cluster, which turned out to be significantly less than previous… Continue reading The Gemini telescope reduced the mass of the heaviest known star

James Webb finds its first cool brown dwarf candidate

The James Webb Infrared Space Telescope has discovered a cool brown dwarf candidate, its first such discovery. The object is located in a thick disk or halo of the Milky Way, its nature should be confirmed by further observations. A preprint of the work was published on arXiv.org. Brown dwarfs occupy an intermediate position between… Continue reading James Webb finds its first cool brown dwarf candidate

ALMA saw the afterglow of a short gamma-ray burst in the millimeter wave for the first time

Astronomers using the ALMA radio telescope system for the first time observed the afterglow of a short gamma-ray burst in the millimeter wavelength range. Such observations make it possible to more accurately determine the parameters of the flare, and are less susceptible to the influence of the interstellar medium and radiation from the host galaxy.… Continue reading ALMA saw the afterglow of a short gamma-ray burst in the millimeter wave for the first time

“James Webb” sent pictures of “Cartwheel”

The James Webb Infrared Space Observatory has captured new images of the Cartwheel, a unique system of two galaxies that collided with each other several hundred million years ago. The images show young clusters and star-forming regions, as well as clouds of dust and gas that make up the “Wheel” structure, according to the observatory’s… Continue reading “James Webb” sent pictures of “Cartwheel”
