How NASA in Silicon Valley will use Webb Telescope to study distant worlds
Feb 01, 2022 (SPX)
On Jan. 24, 2022, the telescope reached its destination, an orbit about one million miles from Earth around a location called Sun-Earth Lagrange point 2, also k...
CU Boulder scientists bring stellar flares into clearer focus
Jan 28, 2022 (SPX)
The most-intense flares, which are more complex than previously observed, could have implications for the viability of life on nearby planets. Ward Howard, a po...
When light loses symmetry, it can hold particles
Jan 28, 2022 (SPX)
This so-called optical force can be designed to point to a certain point in space, where the particle will be held. In fact, the optical trapping technique has ...
Nearly 1,000 mysterious strands revealed in Milky Way's center
Jan 27, 2022 (SPX)
Stretching up to 150 light years long, the one-dimensional strands (or filaments) are found in pairs and clusters, often stacked equally spaced, side by side li...
Instant turn-over of magnetism by gyro motion of relativistic electrons
Jan 27, 2022 (SPX)
Although the mechanisms involved in the origin of magnetic fields in space are still uncertain, one of the widely accepted plausible scenarios is the turbulent ...
New MeerKAT radio image reveals complex heart of the Milky Way
Jan 27, 2022 (SPX)
The image captures radio emission from numerous phenomena, including outbursting stars, stellar nurseries, and the chaotic region around the 4 million solar mas...
Webb Telescope has reached its destination now what
Jan 26, 2022 (SPX)
Right around the time this article is published, it's expected Webb will have reached a place called the Earth-Sun "second Lagrange point", or "L2". This is a p...
Berkeley astronomers set to put Web Telescope through its paces
Jan 26, 2022 (SPX)
After months of anxiety about whether the $10 billion telescope - 25 years in the making and the successor to the highly successful Hubble Space Telescope - wou...
Making matter from collisions of light
Jan 26, 2022 (SPX)
The researchers accelerated two beams of gold ions to close to the speed of light in opposite directions. At such speeds, each gold ion is surrounded by particl...
UW alum helped pack James Webb telescope for space travel
Jan 26, 2022 (SPX)
The telescope, the world's largest and most powerful space science observatory, launched on Dec. 25, starting its journey toward its destination about 1 million...
Orbital Insertion Burn a Success, Webb Arrives at L2
Jan 25, 2022 (SPX)
The final mid-course burn added only about 3.6 miles per hour (1.6 meters per second) - a mere walking pace - to Webb's speed, which was all that was needed to ...
Webb telescope reaches final destination, a million miles from Earth
Jan 24, 2022 (AFP)
At around 2:00 pm Eastern Time (1900 GMT), the observatory fired its thrusters for five minutes to reach the so-called second Lagrange point, or L2, where it wi...
Webb telescope reaches destination, 1 mn miles from Earth
Jan 24, 2022 (AFP)
At around 2:00 pm Eastern Time (1900 GMT), the observatory fired its thrusters for five minutes in order to reach the so-called second Lagrange point, or L2, wh...
New location, same ASIM
Jan 22, 2022 (ESA)
The Atmosphere-Space Interactions Monitor, or ASIM for short, measures electric events in Earth's upper atmosphere with cameras, photometers and X- and gamma-ra...
Worldwide coordinated search for dark matter
Jan 21, 2022 (SPX)
Analysis of data from a one-month continuous GNOME operation has not yet yielded a corresponding indication. However, the measurement allows to formulate constr...
ASU astronomer finds star fuel surrounding galaxies
Jan 20, 2022 (SPX)
In a recently published study, Arizona State University astronomer Sanchayeeta Borthakur has identified the faint fuel reservoirs that surround galaxies, and ho...
Capturing all that glitters in galaxies with NASA's Webb
Jan 20, 2022 (SPX)
The telescope will also provide a few key "puzzle pieces" that were missing until now. "JWST touches on so many different phases of the stellar life cycle - all...
ALMA Catches Intruder Redhanded in Rarely Detected Stellar Flyby Event
Jan 14, 2022 (SPX)

A cosmic romance written in the stars
Jan 14, 2022 (SPX)
It has long been a mystery how some spiral galaxies obtained their central black hole. By combining visible and X-ray observations, astronomers have now discove...
Hubble views a tranquil galaxy with an explosive past
Jan 14, 2022 (SPX)
These cataclysmically violent events take place at the end of the lives of massive stars and can outshine entire galaxies for a short period. While supernovae m...
