The Soho ground-based telescope has recorded one of the largest episodes of volcanic activity on Jupiter’s moon Io. It began in July last year and lasted about six months, accompanied by the release of a substance on Wednesday near the satellite. These observations are important not only for scientists, but also for the automatic station…

In this mission, Edward White became the first American astronaut to make a spacewalk. White and McDivitt spent a lot of time observing the Earth and photographing it.

Some photos of winter Mars from the MRO mission. The frost that can be seen on sand dunes and craters mainly consists of dry ice. As for the characteristic dark spots, these are traces of spring “eruptions”. With an increase in temperature, dry ice sublimates, and jets of carbon dioxide escaping from under the surface…

The explosion gave rise to a powerful cosmic “firework”, the energy of which would be enough for the Sun to shine for 10 million years. At the same time, the gas of the former nebula moves at a speed of 150 kilometers per second away from the epicenter of the explosion, which is approximately equal…

Here is a color image of the craters Munch (bottom) and Sander (top), located in the area of the Plain of Heat on the surface of Mercury. The bottom of the 50-kilometer Sander crater is covered with light material, and the 58-kilometer Munch crater has a dark “rim”. It may seem that the white material…

Scientists together with astronomers of the Keck Observatory are investigating the formation and behavior of clouds of Saturn’s largest satellite. The image on the left uses a filter that allows you to look beyond the lower layers of the atmosphere. Bright spots are clouds in the northern hemisphere. On the right is a color composite…

The infrared image of Saturn and Titan, which was obtained on May 7, 2009 by the Gemini North Observatory team using the Altair adaptive optics system with a near—infrared imaging device (NIRI), is a complete aesthetic delight.⠀Along the perimeter of the massive ring, the outer ring F is faintly visible, which was first detected in…

Astronomers have discovered a new warm Jupiter HD 167768b around an old evolved giant star. It is expected that in the next 150 million years, the expanding luminary will absorb the exoplanet. HD 167768 is 5.3 billion years old. The star belongs to the spectral class G8 III and has a mass of 1.08 solar…

The algorithm was applied to data obtained using the Zwicky Transient Facility, a sky survey instrument based at the Palomar Observatory of the California Institute of Technology. “We needed help, and we knew that as soon as we taught our computers to do this work, they would take a lot of load off us,” the…

The star lost its outer shell less than a few thousand years ago. Astronomers have determined that the Gamma Dove star in the Milky Way is not an ordinary star, but a unique object — the bare core of a massive star that lost its outer shell several thousand years ago due to interactions with…
