Mini-Neptunes and super-Earths up to four times the size of our own are the most common exoplanets orbiting stars beyond our solar system. Until now, super-Earths were thought to be the rocky cores of mini-Neptunes whose gassy atmospheres were blown away. In a new study published in , astronomers from 91社区 show that some of these exoplanets never had gaseous atmospheres to begin with, shedding new light on their mysterious origins.

The threshold for dangerous global warming will likely be crossed between 2027 and 2042 鈥� a much narrower window than the Intergovernmental Panel on Climate Change鈥檚 estimate of between now and 2052. In a study published in , researchers from 91社区 introduce a new and more precise way to project the Earth鈥檚 temperature. Based on historical data, it considerably reduces uncertainties compared to previous approaches.

A Canadian-led team of astronomers, including researchers from 91社区, has discovered that a repeating fast radio burst (FRB) originating from a nearby galaxy pulses at regular intervals.
Researchers within the (CHIME) Fast Radio Burst Collaboration used the CHIME telescope in British Columbia to show that the repeating radio source known as FRB 180916.J0158+65 鈥� first discovered in 2018 by the same group - pulsates apparently every 16.35 days.

Astronomers have pinpointed for the first time the home galaxy of a Fast Radio Burst, moving scientists a step closer to detecting what causes these powerful but fleeting pulses of radio waves. FRBs, which last just a few thousandths of a second, have puzzled astrophysicists since their discovery a decade ago.

Astronomers for the first time detect repeat 鈥榝ast radio bursts鈥� from same sky location
Astronomers for the first time have detected repeating short bursts of radio waves from an enigmatic source that is likely located well beyond the edge of our Milky Way galaxy.聽The findings indicate that these 鈥渇ast radio bursts鈥� come from an extremely powerful object which occasionally produces multiple bursts in under a minute.
