Saturn didn’t always have rings, according to new analysis of Cassini data

Saturn's rings are younger than previously believed, according to new data gathered from the Cassini mission. The rings are certainly less than 100 million years old and perhaps as young as 10 million years old.

How long is a day on Saturn? Scientists finally have an answer

The length of Saturn's day has always been a challenge to calculate because of the planet's non-solid surface and magnetic field. But now scientists have tracked vibrations in the rings to pin down a final answer.

Glowing space billboards could show ads in the night sky

Look up at the night sky in 2020 and you might see an ad for McDonald's floating among the stars. A Russian startup is working on a project that uses a constellation of small satellites in low-Earth orbit to create glowing ads.

Scientists debate mysterious flash of light in space, known as ‘The Cow’

On June 16, 2018 there was an unusual flash in the sky which puzzled astronomers around the world. NASA researchers have been collecting data on the event and have shared two competing theories for what could have caused it.

Dark matter heats up and moves around in dwarf galaxies during star formation

The exact nature of dark matter is one of the enduring questions of physics. Now a team from the University of Surrey, UK, have discovered that dark matter can be heated up and moved around due to star formation within galaxies.

Nearby dwarf galaxy will collide with Milky Way, awaken black hole at its heart

In two billion years' time the Milky Way will collide with the Large Magellanic Cloud (LMC), waking the dormant black hole at the heart of our galaxy and causing it to devour nearby gases and grow in size by ten times.

Artificial soil made from lava rock allows growing of food in space

New research has succeeded in growing plants in high-tech planters which use artificial soil made from lava rock. Researchers have recorded the ways that plants adapt to conditions similar to those in space such as low levels of nitrogen.

Why are there no hot Neptunes? Atmospheric escape could be the culprit

There is an notable absence of hot planets the size of Neptune. New research suggests that this may be due to atmospheric escape: the loss of atmospheric gases like hydrogen into space because of the energy of nearby stars.

Ancient ‘fossil cloud’ could shed light on formation of the early universe

A fossilized cloud of gas left over from the Big Bang has been discovered. The distant cloud is one of only three known fossil clouds in the universe, and could provide valuable information about the formation of the earliest galaxies.

Researchers find a way to ‘see’ dark matter

Two astronomers have come up with a way to "see" dark matter. They used data from the Hubble telescope to look at a faint source of light called intracluster light, which is believed to be distributed in the same locations as dark matter.

Research into how plants respond to microgravity could help grow food in space

A difficulty with growing plants during spaceflight is that plants behave strangely in space, and we are not quite sure why. Now researchers at the University of Florida have made a breakthrough in understanding this process.
