How Knot Theory Can Help Spacecraft Can Change Orbits Without Using Fuel April 29, 2024
When a spacecraft arrives at its destination, it settles into an orbit for science operations. But after the primary mission is complete, there might be other interesting orbits where scientists would like to explore. Maneuvering to a different orbit requires fuel, limiting a spacecraft’s number of maneuvers. Researchers have discovered that some orbital paths allow […]

Another New Molecule Discovered Forming in Space April 29, 2024
The list of chemicals found in space is growing longer and longer. Astronomers have found amino acids and other building blocks of life on comets, asteroids, and even floating freely in space. Now, researchers have found another complex chemical to add to the list. The new chemical is known as 2-methoxyethanol (CH3OCH2CH2OH). It’s one of […]

JWST Uses “Interferometry Mode” to Reveal Two Protoplanets Around a Young Star April 29, 2024
The JWST is flexing its muscles with its interferometry mode. Researchers used it to study a well-known extrasolar system called PDS 70. The goal? To test the interferometry mode and see how it performs when observing a complex target. The mode uses the telescope’s NIRISS (Near Infrared Imager and Slitless Spectrograph) as an interferometer. It’s […]

A Cold Brown Dwarf is Belching Methane Into Space April 29, 2024
Brown dwarfs span the line between planets and stars. By definition, a star must be massive enough for hydrogen fusion to occur within its core. This puts the minimum mass of a star around 80 Jupiters. Planets, even large gas giants like Jupiter, only produce heat through gravitational collapse or radioactive decay, which is true […]

Measuring Exoplanetary Magnetospheres with the Square Kilometer Array April 29, 2024
Life on Earth would not be possible without food, water, light, a breathable atmosphere and surprisingly, a magnetic field. Without it, Earth, and its inhabitants would be subjected to the harmful radiation from space making life here, impossible. If we find exoplanets with similar magnetospheres then those worlds may well be habitable. The Square Kilometer […]
