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.

Unusual atom helps in search for Universe's building blocks

Scientists say the unusual atom - made up of an ordinary caesium atom and an elementary particle called a muon - may prove essential in better understanding the Universe's fundamental building blocks.

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.

Is there life on Mars? Our rovers might not be able to tell

Scientific instruments currently deployed on Mars may lack the sensitivity to identify possible traces of life in this environment.

Unknown class of water-rich asteroids identified

New astronomical measurements in the infrared range have led to the identification of a heretofore unknown class of asteroids. They are located in the asteroid belt between Mars and Jupiter and are - similar to the dwarf planet Ceres - rich in water.

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.

Scientists observe high-speed star formation

New observations have brought to light that stars can form through the dynamic interaction of gas within interstellar gas clouds. This process unfolds faster than previously assumed.

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.
