The first South Korean lunar probe sent the first photo of the Earth and the Moon

The Danuri probe, which became South Korea's first lunar probe, sent back to Earth the first image of the Earth and the Moon. Thus, engineers confirmed the functionality of the camera, which examined the far side of the Moon from an unusual distance, according to the website of the Korean Astronomy and Space Science Institute… Continue reading The first South Korean lunar probe sent the first photo of the Earth and the Moon

James Webb takes its first direct image of an exoplanet

The James Webb Infrared Space Observatory has captured its first direct image of superjupiter HIP 65426b as it orbits the yellow-white dwarf in a wide orbit. The image made it possible to clarify the parameters of the planet and prove the high efficiency of the observatory in direct observations of exoplanets. A preprint of the… Continue reading James Webb takes its first direct image of an exoplanet

Astronomers have limited the lifetime of the first “intra-Venus” asteroid

Astronomers presented the results of studies of the recently discovered asteroid Ailohchahnim, whose orbit lies entirely within the orbit of Venus. It turned out that the body has a diameter of 1.7 kilometers, it can be classified as a silicate asteroid and in 1-2 million years it can collide with the inner planets or even… Continue reading Astronomers have limited the lifetime of the first “intra-Venus” asteroid

The first launch of the SLS rocket was postponed due to a hydrogen leak

The first flight of the SLS super-heavy launch vehicle carrying the Orion spacecraft was postponed due to problems with a hydrogen leak in one of the rocket's core stage engines. The new launch date is set for September 2, 2022. The first launch attempt was broadcast on YouTube. Artemis 1 is the first flight of… Continue reading The first launch of the SLS rocket was postponed due to a hydrogen leak

Starlink satellites will be able to connect directly to regular smartphones

The new generation of Starlink satellites will allow anyone with a smartphone to connect to the mobile network and the Internet, even from places where there is no terrestrial coverage. The connection speed will be from two to four megabits per second. This was announced by SpaceX CEO Elon Musk and T-Mobile President Mike Sievert.… Continue reading Starlink satellites will be able to connect directly to regular smartphones

A candidate for an artificial radio signal from an Earth-like exoplanet turned out to be of terrestrial nature

Astronomers have concluded that the unusual narrow-band radio signal recorded in the direction of the Kepler-438 exoplanet system last year by the FAST telescope is not a technosignature, but is of anthropogenic origin. This is indicated by the polarization properties of the signal. A preprint of the work was published on arXiv.org. To answer the… Continue reading A candidate for an artificial radio signal from an Earth-like exoplanet turned out to be of terrestrial nature

Planetologists have confirmed the possibility of delivering volatile substances to the young Earth by asteroids

Planetologists presented new results from analyzing soil particles from the Ryugu asteroid in laboratory conditions. It turned out that the temperature inside Ryugu’s parent body could not exceed 30 degrees Celsius, and asteroids like Ryugu could indeed deliver volatile substances to the young Earth. Article published in the magazine Nature Astronomy.The near-Earth 900-meter asteroid Ryugu,… Continue reading Planetologists have confirmed the possibility of delivering volatile substances to the young Earth by asteroids

One of the Trojans for the Lucy station turned out to be an asteroid with a satellite

Astronomers have summed up their observations of the occultation of the background star by the Trojan asteroid Jupiter Polymela, which was chosen as one of the targets for the interplanetary station Lucy. Their results confirmed the discovery of a satellite with a diameter of 5 kilometers around the asteroid, which is located at a distance… Continue reading One of the Trojans for the Lucy station turned out to be an asteroid with a satellite

TESS finds an unusually light mini-Neptune

Astronomers using ground-based and space-based telescopes have confirmed the discovery of mini-Neptune GJ 3090b by the TESS space telescope. The exoplanet turned out to be very light, which indicates large reserves of volatile substances, and its atmosphere will be the subject of future studies by the James Webb Telescope. The preprint is published on arXiv.org.… Continue reading TESS finds an unusually light mini-Neptune

Vertical eye sockets gave large carnivorous dinosaurs a strong skull for powerful bites

The paleontologist analyzed a large sample of skulls from dinosaurs and their relatives and found that most species had rounded eye sockets, but large predators such as Tyrannosaurus and Allosaurus had vertically elongated eye sockets. Eye sockets of this shape reduced the load on the skull during a bite, but the eyes became smaller, since… Continue reading Vertical eye sockets gave large carnivorous dinosaurs a strong skull for powerful bites
