By Earl on 25 Feb 2020 No CommentsA 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
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 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.

Yerkes Observatory future to be discussed Feb. 25 at Williams Bay High School
WILLIAMS BAY — Future plans for Yerkes Observatory could be presented later this month at a public meeting at Williams Bay High School.
Mysterious radio bursts from a nearby spiral galaxy
Fast radio flashes still pose something of an enigma to astronomers. Although they only emit for milliseconds at a time, hundreds have been observed in the sky. Only four such Fast Radio Bursts (FRB) have been precisely located so far. Now astronomer have traced the source of a newly discovered FRB to a nearby spiral galaxy similar to our own Milky Way, a galaxy half a billion light-years from Earth, making it the closest FRB to Earth ever localized. The burst called FRB 180916.J0158+65 was observed by a group of eight radio telescopes, including the 100-meter Effelsberg telescope.
