This artist’s concept shows the red supergiant star Betelgeuse and an orbiting companion star. The companion, which is orbiting clockwise from this point of view, generates a dense wake of gas that expands outward.

Hubble Telescope spies 'wake' of supergiant Beutelgeuse's hidden companion star

By Julian Dossett published

Using new observations from the Hubble Space Telescope and observatories on Earth, scientists have confirmed the existence of Betelgeuse's elusive companion star, named Siwarha.

The location of Cloud 9, a "failed galaxy" packed with gas and dark matter but absent of stars

Hubble telescope discovers a new type of cosmic object and astronomers are on 'Cloud 9'

By Robert Lea published

"This is a tale of a failed galaxy."

Stars
A cluster of stars inside a large nebula. The clouds of gas and dust are predominantly bright red in colour and wispy, akin to flames. They are clumped in the bottom-left corner. Other clouds, deeper in the cluster behind many of the stars, appear pale pink. The stars are concentrated in the top half of the image and are mostly small, bright white and six-pointed. They cast blue light over the nebula. Other stars with very long spikes surrounding them lie in the foreground.

A Hubble image of Dracula’s Chivito, the largest protoplanetary disk ever seen

'Dracula's Chivito' looks stunning in this tasty Christmas photo from the Hubble Telescope

Planet-eating stars hint at Earth's ultimate fate

By Matthew R. Francis published

A sampling of aging Sun-like stars demonstrates that they likely eat their closest planets.

Illustration of a hypothesized event known as a superkilonova. A massive star explodes in a supernova (left), which generates elements like carbon and iron. In the aftermath, two neutron stars are born (middle), at least one of which is believed to be less massive than our Sun. The neutron stars spiral together, sending gravitational waves rippling through the cosmos, before merging in a dramatic kilonova (right). Kilonovae seed the universe with the heaviest elements, such as gold at platinum, which glow with red light.

Astronomers may have spotted the 1st known 'superkilonova' double star explosion

By Robert Lea published

"We do not know with certainty that we found a superkilonova, but the event nevertheless is eye-opening."

Astronomers capture 1st direct images of collisions in a nearby star system: 'It's like looking back in time'

By Robert Lea published

"It's like looking back in time in a sense, to that violent period of our solar system when it was less than a billion years old."

Astronomers capture close-up images of nova explosions on 2 dead stars in unprecedented detail

By Keith Cooper published

The nova eruptions come about when a white dwarf steals too much matter from a close red giant companion.

57 ways to capture a dying star: Astronomers get a glimpse of what will happen when our sun dies

By Robert Lea published

"With ALMA, we can now see the atmosphere of a dying star with a level of clarity in a similar way to what we do for the sun."
