Hubble's Advanced Camera for Surveys Instrument resumes science, investigation continues
Nov 09, 2021 (SPX)
Over the past week, the mission team has continued investigating the root cause of the synchronization issues and has seen no additional problems. The team will...
Ultra-precise magnetic field detection using squeezed light
Nov 08, 2021 (SPX)
In many cases, the sensitivity of these instruments is limited by random variations (noise) in the laser light used. If that noise can be reduced, the magnetome...

New great observatories, including Lynx, top ranked by Decadal Survey
Nov 05, 2021 (SPX)
The Lynx X-Ray Observatory is included as part of this vision. Dozens of scientists and engineers at the Center for Astrophysics | Harvard and Smithsonian teame...
Star formation of Universe follows a simple mathematical formula commonly found in nature
Nov 05, 2021 (SPX)
A recent study led by Dr. Antonios Katsianis, a researcher at the Tsung-Dao Lee Institute, Shanghai Jiao Tong University, has compiled observations of million g...
Next Generation Very Large Array strongly endorsed by Decadal Survey
Nov 05, 2021 (SPX)
The ngVLA is a system of 263 dish antennas spread across the entire extent of North America and concentrated in the U.S. Southwest that will provide dramatic ne...
Next space telescope should exceed James Webb' s ability to study planets
Nov 04, 2021 (UPI)
"This large strategic mission is of an ambitious scale that only NASA can undertake and for which the U.S. is uniquely situated to lead," according to the Natio...
The Road to Launch and Beyond for NASA's James Webb Space Telescope
Nov 03, 2021 (SPX)
These preparations are expected to last 55 days from the observatory's arrival by ship to the day of launch. After Webb arrived at the Arianespace clean room fa...
Groundbreaking findings in hunt for new neutrinos in the universe
Nov 02, 2021 (SPX)
Neutrinos, which come in three known "flavors," are smaller than atoms and are one of the most plentiful fundamental building blocks in the universe. Scientists...
Hubble remains in safe mode, NASA team investigating
Nov 02, 2021 (SPX)
Hubble's science instruments issued error codes at 1:46 a.m. EDT Oct. 23, indicating the loss of a specific synchronization message. This message provides timin...
A new way to generate light using pre-existing defects in semiconductors
Nov 02, 2021 (SPX)
A type of group-III element nitride-based light-emitting diode (LED), indium gallium nitride (InGaN) LEDs were first fabricated over two decades ago in the 1990...
Need for Larger Space Telescope inspires lightweight flexible holographic lens
Oct 27, 2021 (SPX)
"We use two spherical waves of light to produce the hologram, which gives us fine control over the diffractive grating recorded on the film, and the effect it h...
Neutron star collisions are a goldmine of heavy elements, study finds
Oct 26, 2021 (SPX)
A new study by researchers at MIT and the University of New Hampshire finds that of two long-suspected sources of heavy metals, one is more of a goldmine than t...
Trapping light with disorder
Oct 26, 2021 (SPX)
Using this concept researchers at Bar-Ilan University in Israel have demonstrated disorder-induced localization, a rather difficult wave phenomenon to observe, ...
Controlling light with a material three atoms thick
Oct 26, 2021 (SPX)
But the control of light can also come in high-tech forms. The screen of the computer, tablet, or phone on which you are reading this is one example. Another is...
New galaxy images reveal a fitful start to the Universe
Oct 25, 2021 (SPX)
One of the most interesting questions that astronomers have been trying to answer for decades is how and when the first galaxies formed. Concerning the how, one...
Hubble gives unprecedented, early view of a doomed star's destruction
Oct 25, 2021 (SPX)
