A super-Earth exoplanet has been detected within the habitable zone of a nearby red dwarf star, where liquid water might exist on its surface under the right atmospheric conditions.

Start-up Vaulted Deep, which just signed a deal with Microsoft, says storing human waste deep underground can keep carbon dioxide out of the atmosphere and pollutants like forever chemicals out of surface ecosystems

An algal bloom in South Australia has caused mass deaths of many species since March - now researchers warn that leafy and weedy seadragons could be facing the threat of extinction

The theorists predict that the beginning of the end will be in about 10 billion years — less than the present age of the universe.

Saturn will be quite distinct in the Pisces constellation.

Less than a decade since the first detection of gravitational waves—ripples in spacetime itself—proposed budget cuts threaten to silence this groundbreaking science

When researchers discovered evidence of “dark oxygen” last year, the news spread around the world, but the biggest challenge to the science comes from its funders

Textbooks say that mitochondria exist to supply cells with energy, but experiments in fruit flies suggest they are also involved in sleep

'Here today, Gorn tomorrow. I think it's now time for other scary things to take their place.'

Marvel's new superhero movie isn't the only thing featuring some of the brightest stars.

A catalog of over 2,000 exploding white dwarf vampire stars, the largest ever gathered, has provided further evidence that dark energy is weakening.

The journey to launch is picking up pace for Europe’s MetOp Second Generation weather satellite – which hosts the Copernicus Sentinel-5 as part of its instrument package. Specialists at Europe’s Spaceport in Kourou have completed the critical and hazardous task of fuelling the satellite, marking a major milestone in its final preparations for liftoff.

Midday seems to be the optimal time to take an oral exam at university, which could be due to students not generally being early risers

Astronomers have discovered a companion star in an incredibly tight orbit around Betelgeuse using the NASA and U.S. National Science Foundation-funded ‘Alopeke' instrument on Gemini North, one half of the International Gemini Observatory, partly funded by the NSF and operated by NSF NOIRLab. This discovery answers the longstanding mystery of the star’s varying brightness and provides insight into the physical mechanisms behind other variable red supergiants.

The New Horizons spacecraft is humanity's fastest-moving spacecraft and headed to interstellar space. Since its exploration of Pluto 10 years ago and subsequent flyby of Arrokoth in 2019, it's been traversing and studying the Kuiper Belt while looking for other flyby objects. That's not all it's been doing, however. New Horizons also has an extended program of making heliophysics observations. The mission science team has also planned astrophysical studies with the spacecraft's instruments. Those include measuring the intensity of the cosmic optical background and taking images of stars such as Proxima Centauri. As the spacecraft moves, the apparent positions of its stellar navigation targets have changed, but that hasn't bothered New Horizons one bit. It knows exactly where it is thanks to 3D observations of those nearby stars.
