NASA NASA’s Hubble Space Telescope entered safe mode May 24 due to an ongoing gyroscope (gyro) issue, suspending science operations. Hubble’s instruments are stable, and the telescope is … Read more
2 min read Hubble Views the Lights of a Galactic Bar This Hubble Space Telescope image reveals details in the barred spiral galaxy NGC 4731. ESA/Hubble & NASA, D. Thilker This new image from the NASA/ESA Hubble Space Telescope shows the broad and sweeping spiral galaxy NGC 4731. It lies in the constellation Virgo and … Read more
NGC 4689 holds an interesting — albeit less royal — place in modern astronomy. The universe is so incredibly vast that at a distance of 54 million light-years NGC 4689 is relatively nearby for a galaxy. This image includes data from two sets of observations, one made in 2019, the other in 2024 , and … Read more
In Webb’s images, the galaxies look like faint red smudges, which is why extra data, known as spectra, were critical for the team’s conclusions. Those spectra show that light from these galaxies is being absorbed by large amounts of neutral hydrogen gas. “The gas must be very widespread and cover a very large fraction of … Read more
5 min read NASA’s Compact Infrared Cameras Enable New Science A new, higher-resolution infrared camera outfitted with a variety of lightweight filters could probe sunlight reflected off Earth’s upper atmosphere and surface, improve forest fire warnings, and reveal the molecular composition of other planets. The cameras use sensitive, high-resolution strained-layer superlattice sensors, initially developed at … Read more
NASA’s Solar Dynamics Observatory captured these images of the solar flare on May 14, 2024 — as seen in the bright flash on the right side. These images show a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in royal blue and gold. This flare shows … Read more
“Webb is really tuned to seeing the infrared wavelengths of light beyond what Hubble can pick up, but Webb cannot see the visible light and the ultraviolet light that Hubble can see, and we need all of those wavelengths of light for studying almost anything ― whether that’s planets, exoplanets, star systems, galaxies, the interstellar … Read more
Remarkably, the 2020 supernova isn’t the only one that astronomers have seen in this galaxy – UGC 9684 has hosted four supernova-like events since 2006, putting it up there with the most active supernova-producing galaxies. It turns out that UGC 9684 is a quite active star-forming galaxy, calculated as producing one solar mass worth of … Read more
The Resolve instrument aboard XRISM (X-ray Imaging and Spectroscopy Mission) captured data from the center of galaxy NGC 4151, where a supermassive black hole is slowly consuming material from the surrounding accretion disk. The resulting spectrum reveals the presence of iron in the peak around 6.5 keV and the dips around 7 keV, light thousands … Read more
“People often ask about this, and simulating these difficult-to-imagine processes helps me connect the mathematics of relativity to actual consequences in the real universe,” said Jeremy Schnittman, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, who created the visualizations. “So I simulated two different scenarios, one where a camera — a stand-in … Read more
