Researchers from Ohio State University have come up with a novel method to detect dark matter, based on existing meteor-detecting technology. By using ground-based radar to search for ionization trails, similar to those produced by meteors as they streak through the air, they hope to use the Earth’s atmosphere as a super-sized particle detector. The results of experiments using this technique would help researchers to narrow down the range of possible characteristics of dark matter particles.Continue reading “The Technique for Detecting Meteors Could be Used to Find Dark Matter Particles Entering the Atmosphere”
Many Next-Generation Telescopes are Carried on Balloons. Here's What the Next Decade Holds in Balloon Astronomy
NASA’s Balloon Program Analysis Group recently presented a roadmap to NASA, to guide them on how to plan and fund future balloon astronomy programs. Balloons have been used for over a century to conduct physics experiments, astronomical observations and Earth observing work, but remain relatively unknown to the general public. Balloon astronomy share many advantages with space telescopes, but at a fraction of the cost.

LICIACube Sends Home Images of the DART Impact and the Damage to Dimorphos
The Light Italian CubeSat for Imaging of Asteroids (LICIACube) has returned a series of close-up images of the asteroid Dimorphos, after last week’s successful impact of the Double Asteroid Redirect Test (DART) probe. LICIACube was built and operated by the Italian Space Agency (ASI), and was designed to capture post-impact imagery for the DART team, to help assess the effects of the impact.Continue reading “LICIACube Sends Home Images of the DART Impact and the Damage to Dimorphos”
Stars Spiral Inward to the Cores of Stellar Nurseries
Astronomers studying a stellar cluster within the Small Magellanic Cloud (SMC) have found young stars spiraling in towards the center of the cluster. The cluster, NGC 346, is an open cluster embedded within a glowing cloud of gas, which is typical of stellar nurseries – places where new stars are formed. The outer spiral arm of this star forming region appears to be funneling gas, dust and new stars into the center, which researchers describe as an efficient way to fuel the birth of new stars.Continue reading “Stars Spiral Inward to the Cores of Stellar Nurseries”
Traveling the Solar System with Pulsar Navigation
A team of researchers at the University of Illinois Urbana-Champaign have found a way for travelers through the Solar System to work out exactly where they are, without needing help from ground-based observers on Earth. They have refined the pulsar navigation technique, which uses X-ray signals from distant pulsars, in a way similar to how GPS uses signals from a constellation of specialized satellites, to calculate an exact position .Continue reading “Traveling the Solar System with Pulsar Navigation”
