NASA launches a new planet-hunting telescope using a giant balloon
NASA launches a new planet-hunting telescope using a giant balloon – TechCrunch A new telescope will seek out planets that resemble Earth from a height of around 125,000 feet, using special optical technology that will filter out light from the stars they orbit to provide a better view. The telescope is the product of UMass…

New Insight into How Much Atmosphere Mars Lost
New Insight into How Much Atmosphere Mars Lost A key tracer used to estimate how much atmosphere Mars lost can change depending on the time of day and the surface temperature on the Red Planet. Previous measurements of this tracer – isotopes of oxygen – have disagreed significantly. Getting an accurate measurement is important…

Astrophysicists Link Brightening of Pulsar Wind Nebula to Pulsar Spin-down Rate Transition—Chinese Academy of Sciences
Astrophysicists Link Brightening of Pulsar Wind Nebula to Pulsar Spin-down Rate Transition—Chinese Academy of Sciences Astrophysicists have discovered that the pulsar wind nebula (PWN) surrounding the famous pulsar B0540-69 brightened gradually after the pulsar experienced a sudden spin-down rate transition (SRT). This discovery, made by a group of astrophysicists led by GE Mingyu and LU…

Black Hole Holograms
Black Hole Holograms A research team from Osaka University, Nihon University and Chuo University has proposed a novel theoretical framework whose experiment could be performed in a laboratory to better understand the physics of black holes. This project can shed light on the fundamental laws that govern the cosmos on both unimaginably small and vastly…
