Nearly 10 billion years ago, the black hole at the center of a galaxy known as PKS B1424-418 produced a powerful outburst. Light from this blast began arriving at Earth in 2012. Now astronomers using data from NASA’s Fermi Gamma-ray Space Telescope and other space- and ground-based observatories have shown… Read more“NASA’s Fermi Telescope Helps Link Cosmic Neutrino to Blazar Blast”
Russian Doll” Galaxy Clusters Reveal Information About Dark Energy
These four galaxy clusters were part of a large survey of over 300 clusters used to investigate dark energy, the mysterious energy that is currently driving the accelerating expansion of the Universe. In these composite images, X-rays from NASA’s Chandra X-ray Observatory (purple) have been combined with optical light from… Read more“Russian Doll” Galaxy Clusters Reveal Information About Dark Energy”
Hubble Peers at a Distinctly Disorganized Dwarf Galaxy
Despite being less famous than their elliptical and spiral galactic cousins, irregular dwarf galaxies, such as the one captured in this NASA/ESA Hubble Space Telescope image, are actually one of the most common types of galaxy in the universe. Known as UGC 4459, this dwarf galaxy is located approximately 11 million light-years away in the… Read more“Hubble Peers at a Distinctly Disorganized Dwarf Galaxy”
Orion Spacecraft Suited Crew Testing
Engineers at NASA’s Johnson Space Center in Houston are evaluating how crews inside a mockup of the Orion spacecraft interact with the rotational hand controller and cursor control device while inside their Modified Advanced Crew Escape spacesuits. The controllers are used to operate Orion’s displays and control system, which the… Read more“Orion Spacecraft Suited Crew Testing”
Study: Long-Term Global Warming Needs External Drivers
Earth’s atmosphere viewed from the International Space Station. A NASA/Duke University study provides new evidence that natural cycles alone aren’t sufficient to explain the global atmospheric warming observed over the last century.

Studying the Solar System with NASA’s Webb Telescope
NASA’s James Webb Space Telescope will look across vast distances to find the earliest stars and galaxies and study the atmospheres of mysterious worlds orbiting other stars. But the observatory also will investigate objects in Earth’s own neighborhood – planets, moons, comets and asteroids in our solar system. These studies… Read more“Studying the Solar System with NASA’s Webb Telescope”
