A recent study led by Aomawa Shields, associate professor of physics and astronomy at the University of California, Irvine, suggests that exoplanets orbiting white dwarf stars could be more habitable than previously assumed. The research, published in The Astrophysical Journal, compares the climates of exoplanets orbiting two different types of stars-a hypothetical white dwarf and Kepler-62, a m

An international team of astronomers has validated the discovery of a super-Earth positioned within the habitable zone of a nearby Sun-like star. Initially detected two years ago by Oxford University scientist Dr. Michael Cretignier, the planet's existence has now been confirmed following an extensive analysis of observational data spanning more than 20 years. The findings, which offer new oppor

A new study challenges the long-held belief that intelligent life is a rare cosmic accident, proposing instead that humanity's emergence was a predictable outcome of Earth's evolving environment. This shift in perspective, led by researchers at Penn State, suggests that conditions for intelligence may arise naturally on other planets as well. The study disputes the "hard steps" model, a fr

From helping catalyze interstellar reactions and fueling the birth of stars to its presence in neighborhood gas giants like Saturn and Jupiter, trihydrogen, or H3+, is best known as the "the molecule that made the universe." While we have a clear picture of how the majority of H3+ is formed - a hydrogen molecule, or H2, colliding with its ionized counterpart, H2+ - scientists are keen to u

New Horizons is healthy and continuing to speed outward across the Kuiper Belt. Our spacecraft is 61 times as far from the Sun as Earth, or over 5.5 billion miles from home! Radio signals, traveling to and from New Horizons at the speed of light - about 186,000 miles per second - take about nine hours to cover that distance. New Horizons is about halfway through a hibernation period that

Asteroids that pass close to Earth often raise concerns about potential collisions, but they also present valuable opportunities for scientific discovery. One such celestial body, the 900-meter-wide asteroid Ryugu, has recently yielded intriguing evidence that may enhance our understanding of life's building blocks in the Solar System. Scientists from Kyoto University have detected salt mi

The European Space Agency (ESA) is ready to guide the ESA/NASA Solar Orbiter spacecraft through its closest encounter with Venus so far.

Today’s flyby will be the first to significantly ‘tilt’ the spacecraft’s orbit and allow it to see the Sun’s polar regions, which cannot be seen from Earth.

Studying the Sun’s poles will improve our understanding of solar activity, space weather, and the Sun-Earth connection.

Lobster-eye satellite Einstein Probe captured the X-ray flash from a very elusive celestial pair. The discovery opens a new way to explore how massive stars interact and evolve, confirming the unique power of the mission to uncover fleeting X-ray sources in the sky.

Jumping workouts could help astronauts prevent the type of cartilage damage they are likely to endure during lengthy missions to Mars and the Moon, a new Johns Hopkins University study suggests. The research adds to ongoing efforts by space agencies to protect astronauts against deconditioning/getting out of shape due to low gravity, a crucial aspect of their ability to perform spacewalks,
