Universe Today

Exoplanets extremely close to their stars are expected to have lost their atmospheres.

The Nancy Grace Roman Space Telescope will use gravitational microlensing to study dark matter.

A history of a planet’s volcanic activity is contained in its rocks.

The Earth’s magnetic field is responsible for shielding us from harmful space weather, including solar radiation from the Sun but also cosmic rays originating from outside our solar system.

For as long as scientists have conducted SETI (Search for Extraterrestrial Intelligence) experiments, parallel efforts in Messaging Extraterrestrial Intelligence (METI) have also been mounted.

Cosmologists have another powerful simulation to work with.

Unlike the Moon, the Sun is constantly rotating from our perspective - but we still only see half of it at any given time.

The magnetic environment around the Sun is a jumbled mess of chaotic fields and streams of charged particles.

Some of the Hubble Space Telescope's earliest observations were of the Orion Nebula.

Almost all meteorites come from asteroids, not the Moon or Mars.

The universe hosts a myriad of star types, including supergiants, giants, main sequence, red dwarfs, brown dwarfs, white dwarfs, and neutron stars.

Get ready for the age of private space telescopes.

Scientists at Imperial College London and Columbia University have found that the largest canyon system in the solar system is still active and shaping Mars today, billions of years after it first formed.

Saudi Arabia is joining the search for alien signals coming from the cosmos.

Scientists have wondered about a connection between Earth's geomagnetic reversals, or pole flips, and mass extinctions.

Typically, when we think of exoplanets, we think of neat spheres floating directly in front of their star, which acts as a giant spotlight.

Professor Erin Kara of MIT's Kavli Institute for Astrophysics and Space Research is helping advance our understanding of the most extreme objects in the Universe by analyzing X-ray reverberations and other astrophysical data.

The Vera Rubin Observatory's Commissioning Camera operated for about 7 weeks in 2024, before the observatory released its well-known first look images.

SMBH jets are driven by thick, hot accretion disks with powerful magnetic fields.

Theory says that during some SMBH mergers, the merger remnant receives a recoil kick from gravitational waves.

Where have all the planets gone?

Private companies are getting better and better at launching more and more mass into space with larger and larger rockets.

The Epoch of Reionization is when radiation from early galaxies and their stars reionized neutral hydrogen and let light travel freely through the cosmos.

Solar flaring is complex behaviour triggered by reconnection, when magnetic field lines break and then snap back to the Sun's surface.

This Webb infrared image, released on October 6th, 2026, shows the star-forming region NGC 7129, about 3,300 light-years from Earth.

Stellar-mass black holes should be in our neighbourhood within about 50 light years of the Solar System.

Figuring out how the Milky Way's thin and thick disks formed is a tough question in astronomy.

In the early Universe, neutrinos interacted strongly with other matter before some of them "decoupled."

Using a planet’s atmosphere to secure a satellite’s place in orbit, a process known as “aerocapture”, has been the dream of flight engineers for decades.

There has been a torrent of solar physics data lately, largely thanks to new spacecraft that have begun actively observing the Sun.

On Earth, water ice is simply water ice.

It may not be as obvious, but just like Earth, Mars has seasons.

Billions of years ago, rain may have helped shape where the chemistry of life could begin on Mars.

JAXA successfully launched its Martian Moon eXplorer on its way to Mars and Phobos.

The region near Sagittarius A-star, the Milky Way's supermassive black hole, is enriched in metals, although only modestly.

Magnetars are neutron stars with magnetic fields a thousand times stronger than normal.

The Moon is slowly cooling and slowly shrinking.

When picturing a star, typically people think of giant balls of burning gas in the sky that emit enough light they are hard to miss.

Young stars form in molecular clouds, and once they're turned on, they begin to shape their natal clouds with radiation.

The NASA/ESA/CSA James Webb Space Telescope Picture of the Month features the brilliant golden galaxies belonging to the MACS J0454.1-0300 galaxy cluster.

The ESA's Euclid space telescope was launched in July, 2026, and its mission is to observe billions of galaxies.

Supermassive black holes power tremendous jets that extend far beyond their galaxy.

Researchers have confirmed the existence of the first microblazar.
