Recently, NSF’s NSO successfully transitioned the processing of these important observations of the Sun’s magnetic field and lower atmosphere to the operational control of NOAA’s Space Weather Prediction Center (SWPC), a move that will ensure reliable delivery of the data to the NOAA’s space weather forecasters who are the nation’s official civilian source for space weather watches, warnings, alerts, and forecasts.
New Brunswick, N.J. (April 21, 2021) – Rutgers University–New Brunswick astrophysicist John P. (Jack) Hughes is available for interviews on a supernova (exploding star) discovery published today in the journal Nature. The discovery, made with NASA’s Chandra X-ray Observatory, features…
Wichita State University’s Dr. Nick Solomey, professor of physics, has been awarded a $2 million grant from NASA for his work on developing a neutrino detector to work in space and close to the sun.
The U.S. NSF’s Daniel K. Inouye Solar Telescope just released its first image of a sunspot. The telescope’s four-meter primary mirror will give the best views of the Sun from Earth throughout the next solar cycle. This image is an indication of the telescope’s advanced optics. The image is released along with the first of a series of Inouye-related articles featured in the Solar Physics Journal.
The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a Rutgers-led study concludes. The study, published in the journal Science Advances, may help resolve what’s known as the faint young sun paradox – a lingering key question in Mars science.
On November 18 scientists from the US National Science Foundation’s National Solar Observatory predicted the arrival of a large sunspot just in time for Thanksgiving. Using a special technique called helioseismology, the team has been “listening” to changing sound waves from the Sun’s interior which beckon the arrival of a large sunspot.
A long time ago – roughly 4.5 billion years – our sun and solar system formed over the short time span of 200,000 years. That is the conclusion of a group of Lawrence Livermore National Laboratory (LLNL) scientists after looking at isotopes of the element molybdenum found on meteorites.
Notre Dame researchers will use data from the new high-speed light detectors to determine the temperature of the sun’s lower atmosphere, measure the spectrum of solar flares and gain a better understanding of the role magnetic fields play in solar flare generation.
When the sun expels plasma, the solar wind cools as it expands through space — but not as much as the laws of physics would predict. UW–Madison physicists now know the reason.
University of New Hampshire researchers use data from NASA’s Parker Solar Probe to observe sun’s plasma and energy build up particles released by solar flares – highlight new phase of energizing process leading to radiation hazards.
Currently, the faint star V Sagittae, V Sge, in the constellation Sagitta, is barely visible, even in mid-sized telescopes. However, around the year 2083, this innocent star will explode, becoming as bright as Sirius, the brightest star visible in the night sky.
Lawrence Livermore National Laboratory (LLNL) scientists and a collaborator from the University of Münster reviewed recent work that shows how meteorites exhibit a fundamental isotopic dichotomy between non-carbonaceous (NC) and carbonaceous (CC – rocks or sediments containing carbon or its compounds) groups, which most likely represent material from the inner and outer solar system.
Researchers at The University of Texas MD Anderson Cancer Center have found that a protein involved in immune response to microbes, TBK1, also can fuel cancer development and suppress immune response to the disease.
About 13 times per century, fleeting Mercury can be seen passing directly in front of the Sun in what is called a transit. The most recent Mercury transit occurred on 11 November 11, 2019. While the path of Mercury across the Sun in fact traced a straight line, in this image the path appears to loop backwards due to an effect called field rotation as the telescope and camera track across the sky.
Stars in the outer reaches of the Milky Way, including our Sun, orbit at an average speed of 130 miles per second. But that’s nothing compared to the most massive spiral galaxies. “Super spirals,” which are larger, brighter, and more massive than the Milky Way, spin even faster than expected for their mass, at speeds up to 350 miles per second.
