Astronomers detect possible radio emission from exoplanet

By monitoring the cosmos with a radio telescope array, an international team of scientists has detected radio bursts emanating from the constellation Booetes. The signal could be the first radio emission collected from a planet beyond our solar system.

A pair of lonely planet-like objects born like stars

Astronomers discovered an exotic binary system composed of two young planet-like objects, orbiting around each other from a very large distance. Although these objects look like giant exoplanets, they formed in the same way as stars, proving that the mechanisms driving star formation can produce rogue worlds in unusual systems deprived of a Sun.

No longer 'faster than permitted by our galaxy'...

Physicists have resolved a long-lasting discrepancy between the measured velocities of interstellar oxygen atoms and other elements in our galaxy: a difference of 380 km/s, which astrophysical measurements of X-ray absorption by oxygen atoms gave, had given astrophysicists a headache.

Can pizza help address the dark matter mystery?

Researchers developed a novel multiple-cell cavity design, dubbed 'pizza cavity'. Just like pizzas are cut into several slices, multiple partitions vertically divide the cavity volume into identical pieces (cells). With almost no volume to be lost, this multiple-cell haloscope enables the meaningful output of high-frequency region scanning.

A huge hourglas structure in the Milky Way

The first all-sky survey performed by the eROSITA X-ray telescope on-board the Spektrum-Roentgen-Gamma observatory has revealed a large hourglass-shaped structure in the Milky Way. These 'eROSITA bubbles' show a striking similarity to the Fermi bubbles, detected a decade ago at even higher energies.

Space weather discovery puts 'habitable planets' at risk

Stellar flares with a chance of radio bursts: that's the weather from Proxima Centauri. New research suggests exoplanets around red dwarf M-type stars will likely be exposed to coronal mass ejections, making the likelihood of finding life as we know it pretty slim.

Researchers discover a new superhighway system in the Solar System

Researchers have discovered a new superhighway network to travel through the Solar System much faster than was previously possible. Such routes could be used to send spacecraft to the far reaches of our planetary system relatively fast, and to monitor and understand near-Earth objects that might collide with our planet.
