Discovered: Remnant of ancient globular cluster that’s ‘the last of its kind’

Discovered: Remnant of ancient globular cluster that’s ‘the last of its kind’ A team of astronomers including Carnegie’s Ting Li and Alexander Ji discovered a stellar stream composed of the remnants of an ancient globular cluster that was torn apart by the Milky Way’s gravity 2 billion years ago, when Earth’s most-complex lifeforms were single-celled […]

Researchers discover triple-layered leading-edge of solar coronal mass ejections

Researchers discover triple-layered leading-edge of solar coronal mass ejections In a study published in The Astrophysical Journal, Dr. MEI Zhixing in Yunnan Observatories of the Chinese Academy of Sciences and his colleagues reported a Magnetohydrodynamical (MHD) numerical study on the coronal mass ejection (CME). They presented a high-resolution 3-D resistive MHD simulation to investigate the […]

Miniature telescope demonstration focuses on sharpening view of distant objects in space

Miniature telescope demonstration focuses on sharpening view of distant objects in space A recently deployed DARPA CubeSat seeks to demonstrate technology that could improve imaging of distant objects in space and allow powerful space telescopes to fit into small satellites. DARPA’s Deformable Mirror (DeMi) CubeSat deployed from the International Space Station July 13, beginning the […]

Extended X-ray emission detected from the radio galaxy 4C 63.20

Extended X-ray emission detected from the radio galaxy 4C 63.20 Using NASA’s Chandra X-ray Observatory, an international team of astronomers has conducted deep imaging observations of a high-redshift radio galaxy known as 4C 63.20. The observational campaign has revealed an extended X-ray emission from this source. The finding is reported in a paper published July […]

Studying radioactive aluminum in stellar systems unlocks formation secrets

Studying radioactive aluminum in stellar systems unlocks formation secrets An international team of astronomers including Stella Offner of the University of Texas at Austin has proposed a new method for the formation of aluminum-26 in star systems that are forming planets. Because its radioactive decay is thought to provide a heat source for the building […]

New evidence for fragmentation of energy release in solar flares

New evidence for fragmentation of energy release in solar flares Type III radio bursts from the sun are signatures of energetic (∼1–100 keV) electrons, accelerated at the reconnection sites, propagating upward through the corona into the interplanetary medium along open magnetic field lines. The emission mechanism of the bursts is widely believed to be due […]

Russia Just Tested an Anti-Satellite Weapon

Russia Just Tested an Anti-Satellite Weapon The United States and Russia/USSR have been adversaries for a long time. Their heated rivarly stretches back to the waning days of WW2, when the enormous Red Army was occupying large swathes of eastern Europe, and the allies recognized the inherent threat. The Cold War followed, when the two […]

Here’s the New Space Force Logo

Here’s the New Space Force Logo The newest branch of the US Military has a logo and a motto now. The mottos is Semper Supra, meaning ‘Always Above’. The logo’s main feature is a delta wing design. The US Space Force is still in its infancy, after being officially created by the US President in […]

Saturn-sized Planet Found in the Habitable Zone of Another Star. The First Planet Completely Discovered by Amateur Astronomers

Saturn-sized Planet Found in the Habitable Zone of Another Star. The First Planet Completely Discovered by Amateur Astronomers Exoplanets have been a particularly hot topic of late.  More than 4000 of them have been discovered since the first in 1995.  Now one more can potentially be added to the list. This one is orbiting Gliese […]

Dead star emits never-before seen mix of radiation

Dead star emits never-before seen mix of radiation A global collaboration of telescopes including ESA’s Integral high-energy space observatory has detected a unique mix of radiation bursting from a dead star in our galaxy—something that has never been seen before in this type of star, and may solve a long-standing cosmic mystery. phys.org Go to […]

This is What an Air-Breathing Electric Thruster’s Intake Would Look Like

This is What an Air-Breathing Electric Thruster’s Intake Would Look Like Like all other technologies, satellite technology has grown in leaps and bounds in the past couple decades. Satellites can monitor Earth in increasingly high resolutions, aiding everything from storm forecasting, to climate change monitoring, to predicting crop harvests. But there’s one thing still holding […]
