Unlike Earth, Maybe Mars Didn’t Form With a Subsurface Magma Ocean

Researchers thought Mars formed — and potentially created a life-supporting atmosphere — like Earth did.

The Universe may not look the same in all directions after all – Astronomy Now

The Universe may not look the same in all directions after all – Astronomy Now

One of the core assumptions all professional and amateur astronomers learn when first entering the field is that at large scales, the universe appears the same in all directions, that is, it’s isotropic.

A paper accepted for publication in Astronomy and Astrophysics suggests that may not be the case.

An international team of researchers using NASA’s Chandra X-ray Observatory, the European Space Agency’s XMM-Newton and other data archives studied the X-ray luminosity of 842 galaxy clusters.

Sub-Neptune sized planet validated with the Habitable-zone Planet Finder

A signal originally detected by the Kepler spacecraft has been validated as an exoplanet using the Habitable-zone Planet Finder (HPF), an astronomical spectrograph built by a Penn State team and recently installed on the 10m Hobby-Eberly Telescope at McDonald Observatory in Texas. The HPF provides the highest precision measurements to date of infrared signals from nearby low-mass stars, and astronomers used it to validate the candidate planet by excluding all possibilities of contaminating signals to very high level of probability. The details of the findings appear in the Astronomical Journal.

SwRI models hint at longer timescale for Mars formation

 

SwRI models hint at longer timescale for Mars formation

The early solar system was a chaotic place, with evidence indicating that Mars was likely struck by planetesimals, small protoplanets up to 1,200 miles in diameter, early in its history. Southwest Research Institute scientists modeled the mixing of materials associated with these impacts, revealing that the Red Planet may have formed over a longer timescale than previously thought.

A Pulsed Discovery In Omega Centauri

A Pulsed Discovery In Omega Centauri

A recent study has unveiled a new discovery at the heart of globular cluster Omega Centauri: five long-anticipated pulsars.

The globular cluster Omega Centauri makes for an impressive sight — millions of stars gravitationally bound into a beautiful sphere, its core alight from the glow of densely packed bodies. A recent study has unveiled a new discovery at the heart of this cluster: five long-anticipated pulsars.
