Multiple telescopes, including Chandra, observed the Milky Way's giant black hole simultaneously with the Event Horizon Telescope (EHT). This combined effort gave insight into what is happening farther out than the field-of-view of the EHT.
Our universe is a chaotic sea of ripples in space-time called gravitational waves. Astronomers think waves from orbiting pairs of supermassive black holes in distant galaxies are light-years long and have been trying to observe them for decades, and now they’re one step closer thanks to NASA’s Fermi Gamma-ray Space Telescope.
Media are invited to meet leaders in space exploration at the 59th annual Robert H. Goddard Memorial Symposium, taking place on the campus of the University of Maryland, College Park, from March 23 to 25. Attendees also have the option to watch the symposium online.
NASA's Neil Gehrels Swift Observatory successfully returned to science operations on February 17. The spacecraft and its three instruments are healthy and operating as expected.
Three individuals with NASA affiliations have received 2022 honors from the American Astronomical Society (AAS), a major international organization of professional astronomers.
On the evening of Tuesday, Jan. 18, NASA's Neil Gehrels Swift Observatory entered into safe mode, suspending pointed science observations. The mission team is investigating a possible failure of one of the spacecraft's reaction wheels as the cause.
Over the past year, NASA has made valuable contributions to Biden-Harris Administration’s goals – leading on the global stage, addressing the urgent issue of climate change, creating high paying jobs, and inspiring future generations.
Using the SOAR Telescope in Chile, astronomers have discovered the first example of a binary system where a star in the process of becoming a white dwarf is orbiting a neutron star that has just finished turning into a rapidly spinning pulsar. The pair is a “missing link” in the evolution of such binary systems.
Vice President Kamala Harris will visit NASA’s Goddard Space Flight Center in Greenbelt, Maryland today, Nov. 5, to get a firsthand look at the agency’s work to combat the climate crisis and protect vulnerable communities.
NASA has selected a new space telescope proposal that will study the recent history of star birth, star death, and the formation chemical elements in the Milky Way.
For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy. Using ground- and space-based facilities, including NASA's Neil Gehrels Swift Observatory, they traced the neutrino to a black hole tearing apart a star, a rare cataclysmic occurrence called a tidal disruption event.
On April 15, 2020, a brief burst of high-energy light swept through the solar system, triggering instruments on many NASA spacecraft. Scientists think the blast came from a supermagnetized stellar remnant located in a neighboring galaxy.
Yellowstone National Park's Old Faithful geyser regularly blasts a jet of boiling water high in the air. Now, an international team of astronomers has discovered a cosmic equivalent, a distant galaxy that erupts roughly every 114 days.
A supermagnetized stellar remnant known as a magnetar blasted out a mix of X-ray and radio signals never observed before. This unique event links magnetars to a phenomenon called fast radio bursts (FRBs) – mysterious, powerful, and usually solitary radio emissions emanating from other galaxies.
Not so long ago, astronomers mapped a galaxy far, far away using radio waves and found it has a strikingly familiar shape. In the process, they discovered the object, called TXS 0128+554, experienced two powerful bouts of activity in the last century.
NASA astrophysicists and engineers are adapting detectors used by earthbound supercolliders and creating them the same way electronics companies produce all modern consumer devices, including cell phones and laptops.
The telltale sign that the black hole was feeding vanished, perhaps when a star interrupted the feast. The event could lend new insight into these mysterious objects.
Astronomers using NASA's Hubble Space Telescope are finding that planets have a tough time forming in the rough-and-tumble central region of the massive, crowded star cluster Westerlund 2.
NASA is naming its next-generation space telescope currently under development, the Wide Field Infrared Survey Telescope (WFIRST), in honor of Nancy Grace Roman, NASA’s first chief astronomer, who paved the way for space telescopes focused on the broader universe.
