Dark Energy Survey Uncovers Clues to Universe’s Complexity
In 1998, astronomers discovered that the universe is accelerating, thanks to a mysterious force called dark energy that makes up about 70% of the universe. The discovery came as a surprise…
Space Oddity: Uncovering the Origin of the Universe’s Rare Radio Circles
Outflowing galactic winds from exploding stars may explain the enormous rings. It’s not every day astronomers say, “What is that?” After all, most observed astronomical phenomena are known: stars, planets,…
NASA’s Hubble Observes Exoplanet Atmosphere Changing Over 3 Years
By combining several years of observations from NASA’s Hubble Space Telescope and conducting computer modelling, astronomers have found evidence for massive cyclones and other dynamic weather activity swirling on a hot,…
Hubble observes a changing exoplanet atmosphere
An international team of astronomers has assembled and reprocessed observations of the exoplanet WASP-121 b that were collected with the NASA/ESA Hubble Space Telescope in the years 2016, 2018 and…
New images reveal what Neptune and Uranus really look like
Neptune is fondly known for being a rich blue and Uranus green – but a new study has revealed that the two ice giants are actually far closer in colour…
Volcanism on Mars: Planet More Active than Previously Thought
University of Arizona researchers reconstructed lava flows from spacecraft images and radar to better understand Mars‘ surprisingly turbulent history. This image taken by the European Space Agency’s Mars Express orbiter…
The Day the Solar Wind Died on Mars
Researchers led by the University of Iowa explain the solar wind’s disappearance on the red planet. The solar wind is a continuous, million-miles-per-hour blast of charged particles from the sun…
Meet the Infrared Telescopes That Paved the Way for NASA’s Webb
The Webb telescope has opened a new window into the universe, but it builds on missions going back 40 years, including Spitzer and the Infrared Astronomical Satellite. Scientists have been…
A New Way to Characterize Habitable Planets
For decades, science fiction authors have imagined scenarios in which life thrives on the harsh surfaces of Mars or our Moon, or in the oceans below the icy surfaces of…
