NASA’s TESS Discovers Planetary System’s Second Earth-Size World

Using data from NASA’s Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet’s surface. The world is 95% Earth’s size and likely rocky. Astronomers previously discovered three planets in […]

Team projects 2 out of 3 glaciers could be lost by 2100

Assistant Professor David Rounce of Civil and Environmental Engineering led an international effort to produce new projections of glacier mass loss through the century under different emissions scenarios. The projections were aggregated into global temperature change scenarios to support adaptation and mitigation discussions, such as those at the recent United Nations Conference of Parties (COP […]

Cyclone researchers: Warming climate means more and stronger Atlantic tropical storms

AMES, Iowa, January 5, 2022 – A warming climate will increase the number of tropical cyclones and their intensity in the North Atlantic, potentially creating more and stronger hurricanes, according to simulations using a high-resolution, global climate model. “Unfortunately, it’s not great news for people living in coastal regions,” said Christina Patricola, an Iowa State […]

Cluster of prehistoric giant marine reptile fossils believed to be birthing grounds

RENO, Nev. – As many as 37 fossilized, school bus-sized marine reptiles from 225 million years ago are clustered in a remote, mountainous desert region of central Nevada in the Berlin-Ichthyosaur State Park. A team of scientists have offered new evidence for solving the decades-old puzzle of why the extinct ichthyosaurs are there. The research, […]

Feline genetics help pinpoint first-ever domestication of cats, MU study finds

COLUMBIA, Mo. December 5, 2022 – Nearly 10,000 years ago, humans settling in the Fertile Crescent, the areas of the Middle East surrounding the Tigris and Euphrates rivers, made the first switch from hunter-gatherers to farmers. They developed close bonds with the rodent-eating cats that conveniently served as ancient pest-control in society’s first civilizations. A […]

First kinetic impact test succeeds in shifting asteroid orbit

The kinetic impact of NASA’s DART spacecraft with the Dimorphos asteroid around its larger Didymos parent body has succeeded in shifting its orbit, meaning humankind’s first planetary defence test has been successful. Observations are continuing of the debris plume caused by the collision for as long as possible, as the asteroid system gradually recedes from Earth. As […]

Impact that killed the dinosaurs triggered “mega-earthquake” that lasted weeks to months

Denver, Colo., USA, 66 million years ago, a 10-kilometer asteroid hit Earth, triggering the extinction of the dinosaurs. New evidence suggests that the Chicxulub impact also triggered an earthquake so massive that it shook the planet for weeks to months after the collision. The amount of energy released in this “mega-earthquake” is estimated at 1023 joules, […]

Webb and Hubble capture detailed views of DART impact

Two of the great space observatories, the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescope, have captured views of a unique experiment to smash a spacecraft into a small asteroid. Observations of NASA’s Double Asteroid Redirection Test (DART) impact mark the first time that Webb and Hubble were used to simultaneously observe the same celestial […]

DART’s Impact with Asteroid Dimorphos (Official NASA Broadcast)

Countdown to impact as NASA’s Double Asteroid Redirection Test (DART) attempts humanity’s first-ever test of planetary defense! The DART spacecraft will intentionally crash into asteroid Dimorphos at 4:14 p.m. PT on Monday, September 26, 2022 to see if kinetic force can change its orbit. Why? If this test is successful, the same technique could be […]

How global warming affects astronomical observations

September 22, 2022 – Astronomical observations from ground-based telescopes are sensitive to local atmospheric conditions. Anthropogenic climate change will negatively affect some of these conditions at observation sites around the globe, as a team of researchers led by the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS reports. The quality […]
