Astronomers discover metal-rich galaxy in early universe
While analyzing data from the first images of a well-known early galaxy taken by the James Webb Space Telescope, astronomers discovered a companion galaxy previously hidden behind the light of the foreground galaxy - one that surprisingly seems to have already hosted multiple generations of stars despite its young age, estimated at 1.4 billion years old.

Galaxies 'too big to even exist' discovered using James Webb Space Telescope
Using the powerful James Webb Space Telescope, astronomers have observed massive candidate galaxies at the beginning of time, up to 100 billion times the mass of the Sun which, if confirmed, would contain more mass than was thought to exist in the whole Universe at that time.

The perfect explosion in space - the mystery of the spherical kilonova
When neutron stars collide, they produce an explosion that, contrary to what was believed until recently, is shaped almost like a perfect sphere. Although how this is possible is still a mystery, the discovery may provide a new key to measuring the age of the Universe.

Space travel influences the way the brain works
Scientists have found how the human brain changes and adapts to weightlessness, after being in space for 6 months. Some of the changes turned out to be lasting - even after 8 months back on Earth.

Does ice in the Universe contain the molecules making up the building blocks of life in planetary systems?
If you want to build a habitable planet, ice is a key ingredient. The ice can be found in enormous clouds in the Universe and it is the main carrier of the necessary elements such as carbon , hydrogen, oxygen, nitrogen and sulphur.

Tadpole playing around black hole
A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a dark object, most likely a black hole 100,000 times more massive than the Sun.

Scientists find first observational evidence linking black holes to dark energy
Searching through existing data spanning 9 billion years, physicists have uncovered the first evidence of 'cosmological coupling' - a newly predicted phenomenon in Einstein's theory of gravity, possible only when black holes are placed inside an evolving universe.
