On Thursday, July 26th, the Hudson River Museum was at Cross County Shopping Center, putting on a series of science projects as part of SummerFest on the Cross County Green. During the “Summer Skies” event, visitors participated in demonstrations and projects and created items to take home. They explored gravity and light, and made of a model of the NuSTAR space telescope.

Black holes are famous for their muscle: an intense gravitational pull known to gobble up entire stars and launch streams of matter into space at almost the speed of light. It turns out the reality may not live up to the hype. University of Florida scientists have discovered these tears in the fabric of the universe have significantly weaker magnetic fields than previously thought.

On August 21, for about two minutes across a swath of North America, Earth's moon will pass in front of and completely block out the sun, causing a total solar eclipse. Countless people are expected to witness this rare phenomenon, the first total solar eclipse in North America in 38 years. Just this week, scientists at Caltech and JPL decided that a small space telescope will be watching with them.

Using NASA’s Chandra X-ray Observatory and other X-ray observatories, astronomers have found evidence for what is likely one of the most extreme pulsars, or rotating neutron stars, ever detected. The source exhibits properties of a highly magnetized neutron star, or magnetar, yet its deduced spin period is thousands of times longer than any pulsar ever observed.

Fiona Harrison, principal investigator of NASA's NuSTAR mission, has been selected to receive the 2016 Massey Award, given by the Committee on Space Research. The Massey Award honors "outstanding contributions to the development of space research in which a leadership role is of particular importance" and honors the memory of Sir Harrie Massey.

Supermassive black holes in the universe are like a raucous choir singing in the language of X-rays. When black holes pull in surrounding matter, they let out powerful X-ray bursts. This song of X-rays, coming from a chorus of millions of black holes, fills the entire sky -- a phenomenon astronomers call the cosmic X-ray background.

The European Space Agency's orbiting X-ray observatory, XMM-Newton, has proved the existence of a "gravitational vortex" around a black hole. The discovery, aided by NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) mission, solves a mystery that has eluded astronomers for more than 30 years, and will allow them to map the behavior of matter very close to black holes. It could also open the door to future investigations of Albert Einstein's general relativity.

Using observations made by X-ray space observatories NuSTAR and Swift/XRT, a team of scientists led by Ashley King (Einstein Fellow at Stanford University) has managed to measure the location of the inner edge of the disk in Aquila X-1, a neutron-star X-ray binary located 17,000 light-years away.

Dr. Lynn R. Cominsky, Professor and Chair of the Department of Physics and Astronomy, joined the faculty at Sonoma State University in 1986 and became chair of the Physics and Astronomy Department in 2004. She also founded Sonoma State’s Education and Public Outreach group in 1999. Previously, she worked with the University of California, Berkeley Space Sciences Laboratory and NASA’s Extreme Ultraviolet Explorer Satellite Project. Dr. Cominsky earned her PhD from the Massachusetts Institute of Technology and her BA from Brandeis University.

NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has captured the best high-energy X-ray view yet of a portion of our nearest large, neighboring galaxy, Andromeda. The space mission has observed 40 "X-ray binaries" -- intense sources of X-rays comprised of a black hole or neutron star that feeds off a stellar companion.

The most massive black holes in the universe are often encircled by thick, doughnut-shaped disks of gas and dust. This deep-space doughnut material ultimately feeds and nourishes the growing black holes tucked inside.

The baffling and strange behaviors of black holes have become somewhat less mysterious recently, with new observations from NASA's Explorer missions Swift and the Nuclear Spectroscopic Telescope Array, or NuSTAR. The two space telescopes caught a supermassive black hole in the midst of a giant eruption of X-ray light, helping astronomers address an ongoing puzzle: How do supermassive black holes flare?

Some of the "biggest and baddest" black holes around are buried under thick blankets of gas and dust. These monsters in the middle of galaxies are actively devouring material, but their hidden nature makes observing them a challenge. NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) recently caught a glimpse of five of these secluded beasts.

For the first time, a mission designed to set its eyes on black holes and other objects far from our solar system has turned its gaze back closer to home, capturing images of our sun. NASA's Nuclear Spectroscopic Telescope Array has taken its first picture of the sun, producing the most sensitive solar portrait ever taken in high-energy X-rays.

Astronomers have discovered strange and unexpected behaviour around the supermassive black hole at the heart of the galaxy NGC 5548. The international team of researchers detected a clumpy gas stream flowing quickly outwards and blocking 90 percent of the X-rays emitted by the black hole. This activity could provide insights into how supermassive black holes interact with their host galaxies.
