The “quarantine fatigue” of 2020 became an ongoing “pandemic fatigue,” a complex set of emotions that continues to affect the nation

How sexual reproduction came about has long been a mystery, but an evolutionary model suggests it could have started with cells fusing to increase their food reserves

The March 13–14 lunar eclipse will be an all-night affair you won’t want to miss

Get the Celestron TrailSeeker 8x42 for their best price in over a year — a fantastic pair of binoculars for skywatching on the go.

Novelist John Green talks about his new nonfiction book, Everything is Tuberculosis, and the inequities in treatment for the highly infectious disease.

Higher latitudes on the moon with slopes facing the poles "are not only scientifically interesting but also pose less technical challenges for exploration in comparison with regions closer to the poles of the moon."

Mosquito-borne diseases like West Nile virus could become a growing concern in the UK and other northern European nations as the climate warms, with a virus affecting blackbirds showing how these pathogens can take hold

At MWC25 Barcelona, the European Space Agency (ESA) unveiled a funding initiative, promoted in partnership with GSMA Foundry, to support projects aimed at integrating satellite and terrestrial networks for seamless connectivity.

We explore the celestial geometry that explains different kinds of eclipses of the sun and the moon.

For the second time in a row, SpaceX lost the second stage of its Starship launch system during a flight test, while recovering the first-stage Super Heavy booster.

An X-ray signal has been detected at the very centre of the Helix Nebula, at the site of its central white dwarf star. It’s a burned out stellar remnant that doesn’t usually emit flashes of X-ray radiation but a new study has been analysing the outburst. The team of researchers think that the stellar corpse smashed into one of its surviving planets and that the X-rays are coming from the planetary debris as it falls onto the surface of the white dwarf.

An ultra-hot Neptune exoplanet has been observed by JWST and the image reveals dramatically different hemispheres. The planet orbits so close to its host start that it is tidally locked so one hemisphere remains facing the star. On this permanent daytime side, temperatures reach 2,000°C but the temperatures plummet on the daytime side. The observations show that the daytime side has bright reflective clouds on its cooler western hemisphere but not on its eastern side!

The Gaia Hypothesis theorizes that all of Earth's systems are tied together, making one large, living organism. While there's still some disagreement about whether or not that hypothesis is true, it is undeniable that many of Earth's systems are intertwined and that changes in one can affect another. As our technology advances, we are becoming more and more capable of detecting changes in those systems and how those changes affect other systems as well. A new proposal from a robotics expert at NASA's Jet Propulsion Laboratory (JPL) takes that exploration one step further by trying to develop a system that takes the "pulse" of a planet.

The upper stage of SpaceX's huge Starship rocket exploded over the Atlantic Ocean this evening (March 6), creating a dramatic sky show for people in The Bahamas, Florida and elsewhere.

The mystery of Dark Matter endures. Despite sixty years of observation and research, scientists still haven't isolated the particle that accounts for roughly 85% of the Universe's mass. However, ongoing experiments and studies have provided insight into how this mysterious mass works. For instance, a research team led by a member of the Tokyo Metropolitan University relied on a new technique that has set new limits on the lifetime of Dark Matter (DM), bringing scientists a step closer to resolving this cosmological mystery.

SpaceX managed to catch the Super Heavy booster on Starship's eighth test flight today (March 6), but the vehicle's upper stage was lost about nine minutes after liftoff.

Skeptics love to bring up one particular topic regarding long-term human space exploration - radiation. So far, all of the research completed on it has been relatively limited and has shown nothing but harmful effects. Long-term exposure has been linked to an increase in cancer, cataracts, or even, in some extreme cases, acute radiation poisoning, an immediate life-threatening condition. NASA is aware of the problem and recently supported a new post-doc from MIT named Robert Hinshaw via the Institute for Advanced Concepts (NIAC) program. Dr. HHinshaw'sjob over the next year will be to study the effectiveness of an extreme type of mitochondria replacement therapy to treat the long- and short-term risks of radiation exposure in space.
