New Telescopes to Study the Aftermath of the Big Bang
Astronomers are currently pushing the frontiers of astronomy. At this very moment, observatories like the James Webb Space Telescope (JWST) are visualizing the earliest stars and galaxies in the Universe, which formed during a period known as the “Cosmic Dark Ages.” This period was previously inaccessible to telescopes because the Universe was permeated by clouds…

Uranus aurora discovery promises new riches from James Webb Space Telescope
After more than 30 years scientists have finally been able to confirm that the icy planet Uranus has an infrared aurora. The discovery will provide insight into how magnetic fields on ice giants such as Uranus and Neptune behave and could even help astronomers use NASA’s James Webb Space Telescope to identify similar aurorae from…

X-ray telescopes show ghostly ‘hand’ in space
RALEIGH, N.C. (WNCN) — Two NASA X-ray space telescopes have joined together to show what looks like the bones of a hand floating in space! This “hand” is what is left of a giant star that collapsed on itself roughly 1500 years ago. When it did that, it formed an object called a neutron star.…

JWST snaps silky new picture of the Crab Nebula
This image by NASA’s James Webb Space Telescope is the Crab Nebula, the remnants of a supernova 6,500 light-years away. The supernova remnant is comprised of several different components, including doubly ionized sulfur (red-orange), ionized iron (blue), dust (yellow-white and green), and synchrotron emission (white).

Salts and Organics Observed on Ganymede’s Surface by NASA’s Juno
NASA’s Juno mission has observed mineral salts and organic compounds on the surface of Jupiter’s moon Ganymede. Data for this discovery was collected by the Jovian InfraRed Auroral Mapper (JIRAM) spectrometer aboard the spacecraft during a close flyby of the icy moon. The findings, which could help scientists better understand the origin of Ganymede and…

Elon Musk’s Starlink satellites are “leaking” signals
When I was a child in the 1970s, seeing a satellite pass overhead in the night sky was a rare event. Now it is commonplace: sit outside for a few minutes after dark, and you can’t miss them. Thousands of satellites have been launched into Earth orbit over the past decade or so, with tens…
