Hubble captures the widest image of COSMOS field in infrared

This is a recently released Hubble's image of the COSMOS field - part of the sky used by astronomers to study the distant universe. It contains pictures of many galaxies, some of them with redshift over 2. That means their light has been stretched by the expansion of the universe into the infrared part of the electromagnetic spectrum.

Hubble telescope spots the most distant star ever observed: 28 billions light years

Thanks to a gravitational lens created by a massive cluster of galaxies astronomers were able to identify the most distant single star ever seen. The star nicknamed Earendel has between 50 and 500 solar masses and lies 28 billion light years away. According to a new study published in Nature magazine, the light detected by Hubble left the star when the universe was less than a billion years old (out of today's 13,8 billion years).

First detection of warm and cold matter escaping a neutron star

Astronomers detected matter escaping neutron star in low-mass X-ray binary Swift J1858.6-0814 (a system containing neutron star and emitting X-rays). The detection was made in the visible and ultraviolet spectrum for the first time. Until now there were only observed systems with escaping cold or hot matter.

Supermassive black hole is driving star formation in nearby galaxy

Supermassive black holes can slow down star formation in galaxies. But they can also be the cause of creating new stars. Such a case is in the center of the dwarf galaxy Henize 2-10. There is a jet of gas originating in the center of the galaxy that is putting a pressure on nearby molecular clouds, which in turn leads to birth of new stars along the way.

First planetary magnetic field detected outside the solar system

Astronomers using the Hubble space telescope detected a magnetic field around the exoplanet for the first time. The planet orbits a star HAT-P-11 124 light years away. The star is smaller than the Sun and the planet is about the size of Neptune.

Persistent signs of water detected in tenuous atmosphere of Europa

Scientists long suspect there is a global ocean under the surface of Europa. It is hidden under a thick ice crust with faults through which water escapes to a very thin atmosphere. New analysis of old Hubble data now show even more water vapor, this time sublimating from surface.

Winds in the Great Red Spot are getting faster

According to data from the Hubble space telescope winds in the biggest storm in the Solar system are getting faster. In last 11 years, which is how long year lasts on Jupiter, the winds at the edge of Great Red Spot got 8 % faster. It's not clear as to what is the cause if this increase. The clues are probably hidden under the jovian cloud cover.

Exoplanet WASP-127 b may contain water molecules hidden under a cloud cover

New analysis of light coming from a star WASP-127 shows a clear signal of water from an exoplanet orbiting it. However the signal is showing only in infrared spectrum, and not in visible. This might be caused by a thick clouds blocking the water signal in visible spectrum.

Milky Way galaxy has large variability in its interstellar medium metalicity

New research shows evidence, that the matter between stars in our galaxy has significant variability in its composition. The ratio of heavier elements is not as homogenous as predicted by computer simulations.

Ongoing thermonuclear fusion on the surface of white dwarfs slows their cooling and changes how we calculate their age

By comparing more than 700 white dwarfs in two different globular clusters, astronomers realized there is ongoing thermonuclear fusion on their surfaces. The unexpected process leads to slower cooling of these white dwarfs which in turn could mean, that we might be wrong about their ages. And the ages of globular clusters they are part of.
