The crowds of Creation and the Eagle Nebula in NASA’s picture of the day
James Webb photographed the Pillars of Creation Thanks to its technical capabilities, the James Webb telescope has the ability to penetrate the dust curtain and capture previously unseen details of the internal structure of nebulae and regions of active star formation. No wonder NASA used it to shoot the Pillars of Creation. The JWST image…

The Solar Orbiter spacecraft captured the solar corona in high resolution
The ESA-led Solar Orbiter mission has experienced its second rendezvous with the Sun. Solar Orbiter was located at a distance of 0.29 AU from the Sun. The corona is the outer atmosphere of the Sun. The photo shows the dynamic nature of the solar corona, incandescent by a million degrees. The solar plasma is in…

The moon could form in just a few hours — that’s how it could happen
It is known that our satellite was formed as a result of the collision of the Earth with a huge object the size of Mars. But it is not known exactly how the Moon formed — it was previously thought that in a few months or even years. The new simulation shows a completely different…

Triple Gravity Lensing by James Webb
The massive gravity of the MACS0647 galaxy cluster acts as a cosmic lens, refracting and magnifying light from the more distant MACS0647-JD system. Due to the triple lensing, we see the system simultaneously in three places, which are marked with numbers and placed in separate blocks on the right (OV1, OV2 and OV3). MACS0647-JD has…

Young star formation complexes have been discovered in the galaxy NGC 4324
Astronomers have been investigating a nearby lenticular galaxy known as NGC4324. They discovered young star formation complexes in the inner ring of this galaxy. NGC4324 (also known as UGC 07451), located about 85 million light-years away in the constellation Virgo, is an early-type lenticular galaxy about 66,000 light-years in size. Its stellar mass is about…

Chandra’s X-ray vision combined with JWST reveals even more details about the Universe
Beyond their beauty, the images provide insight into the inner workings of some of the most complex astrophysical phenomena in the universe. Scientists have not yet studied the images and have not published their research, but we can already draw some conclusions. X—ray radiation tells us where high-energy processes are taking place, and infrared radiation…

Comet C/2017 K2 (PanSTARRS)
Comet C/2017 K2 (PanSTARRS) is approaching the perihelion point – the closest approach to the Sun – which will occur on December 20. It sails through the skies of the southern hemisphere of the planet, remaining a good object for observation with a telescope. In this picture, its greenish coma and whitish dust tail are…

Signs of DNA mutation found in astronauts’ blood
Flying into space can increase the risk of cancer. American scientists from the Icon Medical School on Mount Sinai analyzed the blood of 14 NASA astronauts. The samples showed signs of somatic DNA mutations. Because of them, the risk of developing cancer and heart disease may increase. On average, astronauts stayed in space for 12…

Observation of the globular cluster RBC EXT8 revealed that its metallicity is much lower than expected
The iron content in a cluster of stars is about 800 times less than in our Sun, which makes us reconsider the model of the formation of such clusters. Metallicity characterizes the age of a star: the fewer metals, the older the star.

Observations of the James Webb telescope gave the first confirmation that there are stone clouds in some alien worlds
In the new study, scientists used the radiation spectrum of a brown dwarf to determine the composition of VHS 1256-1257 b. The study showed that water, methane, carbon monoxide and carbon dioxide, sodium and potassium are common in the atmosphere of the brown dwarf. Inside the atmosphere, scientists were able to detect clouds of silicates.…
