How Will Martian Gravity Affect Skeletal Muscle?

Marie Mortreux, an assistant professor in the University of Rhode Island’s College of Health Sciences, is part of an international team of researchers studying how the Mars’s gravity would affect astronauts’ skeletal muscle.

Saturn-mass world discovered orbiting two low-mass stars

You just established a settlement on an Earth-like planetary body far from our solar system. You did your evening chores after eating dinner, and you want to go out for the evening view, which consists of two setting stars, reminiscent of the infamous scene in Star Wars. However, there’s one major difference: a large planetary body is in the sky. As you were aware before arriving, you’re on an exomoon orbiting a Saturn-sized exoplanet, both of which orbits two stars.

This Pair Of Brown Dwarfs Can't Get Enough Of Each Other

Astronomers have found the first case of a brown dwarf binary pair experiencing mass transfer. The pair are very close to one another, with an orbital period of only 57 minutes. The pair will eventually merge into one, brighter star, or the accretor will become massive enough to trigger fusion. At only 1,000 light-years away, the system is a strong candidate for more detailed, follow-up observations.

This Super-Puff Planet is Hiding its True Nature Behind Thick Haze

Super-puff planets have extremely low densities, and exoplanet scientists aren't sure why. They seem to defy our understanding of how planets form. Researchers used the JWST to observe the atmosphere of Kepler-51d, one of the puffiest of the super-puffs. Unfortunately, even the powerful space telescope found a featureless spectrum. What does it mean?

The Sun’s Long-Lived Active Regions Are Massive Flare Factories—But We Don’t Know Why

Space weather is a fascinating subject, but one we still have a lot to learn about. One of the main components of it is the active regions (ARs) of the Sun. These huge concentrations of magnetic fields show up throughout the Sun’s photosphere and are the primary source of solar flares and coronal mass ejections (CMEs). They can be simple pairings of magnetic flux or huge, magnetically complex tangles that spend weeks creating massive solar storms before dissipating. But tracking the longest lived of these ARs has been a headache for solar physicists, and a recent paper by Emily Mason and Kara Kniezewski, published in The Astrophysical Journal, both dives into this tracking problem and uncovers some interesting features of the Sun’s most persistent ARs.

Canada Allocates $200 Million Towards the Creation of Nation's First Spaceport

Minister of National Defence David McGuinty announced on Monday, March 16th, that the Canadian government is committing $200 million to develop Canada's first commercial spaceport in Nova Scotia, which will be run by Maritime Launch Services.

The Crab Pulsar's Puzzling Emissions Finally Explained.

Pulsars are rapidly rotating neutron stars. The Crab Pulsar, an often studied supernova remnant, is known for its unusual radio emission patterns. New researchs says it's because of a "tug-of-war" between magnetism and gravity. Gravity acts as a focusing lens and plasma in the magnetosphere acts as a defocusing lens.
