Nearby galaxies suggest the universe may be expanding more slowly than thought
For decades, scientists have tried to measure how fast the universe is expanding.
This expansion rate is known as the Hubble constant, and it plays...
Astronomers discover powerful “cosmic laser” shining from halfway across the universe
Astronomers using a powerful radio telescope in South Africa have discovered an extraordinary cosmic signal coming from more than 8 billion light-years away.
The signal...
Astronomers discover alcohol-rich interstellar comet passing through our solar system
Astronomers studying a rare interstellar comet have discovered something surprising: it contains unusually large amounts of methanol, a type of alcohol.
The discovery offers a...
Why are some stars always visible while others come and go with the seasons
As a space scientist, every time I go outside with my family, I tell my children to look up at the sky.

How old is the universe?
Scientists have long tried to answer this question, but different measurement methods have produced conflicting results.
Now, researchers from the University...
The coldest ‘stars’ in the galaxy might actually be alien megastructures
Ever since physicist Freeman Dyson first proposed the concept in 1960, the "Dyson sphere" has been the holy grail of techno-signature hunters.
A highly advanced...
Scientists spot unexpected cold region inside Jupiter’s northern lights
Jupiter’s northern lights are the most powerful in the solar system, but new observations from the James Webb Space Telescope (JWST) have revealed surprising...

Scientists discover how black hole radiation could help life thrive
At the center of most large galaxies, including our Milky Way, sits a supermassive black hole.
These powerful objects sometimes enter active galactic nucleus (AGN)...
How planetary nebulae get their shapes
About 7.5 billion years from now, our sun will have converted most of its hydrogen fuel into helium through fusion, and then burned most...
Scientists explore the real impact of Starlink Satellites
Since 2019, SpaceX has been launching an increasing number of internet satellites into orbit around Earth.
The satellite constellation, called Starlink, now includes nearly 1,800...
Astronauts could take an asteroid ferry from Earth to Mars
This idea really is quite a fascinating one.
Currently a trip to Mars would require large amounts of air, water and other resources to sustain...
How did supermassive black holes get so big, so early
Supermassive Black Holes (SMBHs) can have billions of solar masses, and observational evidence suggests that all large galaxies have one at their centres.
However, the...
