A team of researchers, including Brown planetary scientist Jim Head, propose using the James Webb Space Telescope to look at five planets in the Venus Zone, a search that could reveal valuable insight...
As praise pours in for the images released July 12 from NASA’s new James Webb Space Telescope (JWST) – the next-generation telescope able to peer deeper into the cosmos – Cornell astronomy faculty who...
A rare and persistent rapid-fire fast radio burst sourcesending out an occasional and informative cosmic ping from more than 3.5 billion light years away – now helps to reveal the secrets of the br...
New research has revealed the solution to Jupiter's 'energy crisis', which has puzzled astronomers for decades. Astronomers have created a detailed global map of the gas giant's upper atmosphere, conf...
Much of the carbon in space is believed to exist in the form of large molecules called polycyclic aromatic hydrocarbons, or PAHs. Since the 1980s, evidence has indicated that these molecules are abund...
USRA is an independent, nonprofit research corporation where the combined efforts of in-house talent and university-based expertise merge to advance space science and technology.USRA was founded in 19...
One of the biggest mysteries in astroparticle physics has been the origins of ultrahigh-energy cosmic rays, very high-energy neutrinos, and high-energy gamma rays. Now, a new theoretical model reveals...
A 60-year-old mystery about the source of energetic, potentially damaging particles in Earth's radiation belts has been solved using data from a shoebox-sized satellite built and operated by students....
While Earth's weather reports center on precipitation, temperature, wind direction and velocity, and humidity, space weather forecasts attempt to predict activity that occurs on the sun -- and how the...
Observation of the hot universe, from 105 K upward, has a vital impact on some of the most fundamental questions in astrophysics today. Hot plasmas, from the sun and stellar coronae to the cores of ga...
Black holes make for a great space mystery. They're so massive that nothing, not even light, can escape a black hole once it gets close enough. A great mystery for scientists is that there's evidence ...
For the first time, scientists worldwide and at Penn State University have detected both gravitational waves and light shooting toward our planet from one massively powerful event in space -- the birt...
A new, low-cost attachment to telescopes allows previously unachievable precision in ground-based observations of exoplanets -- planets beyond our solar system. With the new attachment, ground-based t...
When a total solar eclipse sweeps across U.S. skies on Monday, Aug. 21, UMass Lowell faculty and students will be stationed around the country, conducting research that will be used to better predict ...
Astronomers have used, for the first time, a novel method to determine the mass of a nearby dead star. The star is a "white dwarf," the shrunken corpse of a star like our sun after it has burned up it...
