Sunshield Successfully Deploys on NASA’s Next Flagship Telescope
On Jan. 4, 2022, engineers successfully completed the deployment of the James Webb Space Telescope’s sunshield, seen here during its final deployment test on Earth in December 2020 at Northrop…
A study shows the unexpected effect of black holes beyond their own galaxies
These results suggest, then, that there is a particular coupling between the black holes and their galaxies, by which they can expel matter to great distances from the galactic centres,…
Magnetized Threads Weave Spectacular Galactic Tapestry
The new panorama of the Galactic Center builds on previous surveys from Chandra and other telescopes. This latest version expands Chandra’s high-energy view farther above and below the plane of…
Bubbles with Titanium Trigger Titanic Explosions
The heat from this cataclysmic event produces a shock wave – similar to a sonic boom from a supersonic jet – that races outwards through the rest of the doomed…

What, precisely, is happening at its core to cause all this activity? Upcoming observations led by Nora Lützgendorf and Macarena García Marín of the European Space Agency using NASA’s James…
New distance measurements bolster challenge to basic model of universe
Observational results inconsistent with theory National Radio Astronomy ObservatoryShare Print E-Mail A new set of precision distance measurements made with an international collection of radio telescopes have greatly increased the likelihood that…
Doubts about basic assumption for the universe
Study by the Universities of Bonn and Harvard questions a fundamental principle of cosmology University of Bonn No matter where we look, the same rules apply everywhere in space: countless…
Hubble Finds Best Evidence for Elusive Mid-Sized Black Hole
From NASA March 31, 2020 Astronomers have found the best evidence for the perpetrator of a cosmic homicide: a black hole of an elusive class known as “intermediate-mass,” which betrayed…
Chandra Data Tests ‘Theory of Everything’
March 19, 2020 One of the biggest ideas in physics is the possibility that all known forces, particles, and interactions can be connected in one framework. String theory is arguably…
