Early observations of Comet C/2019 Q4, which will likely be declared the first confirmed interstellar comet, suggest that its composition is pretty similar to that of comets found in our own solar system.

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 to estimate how much atmosphere Mars once had before it was lost.

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 Fangjun at the Institute of High Energy Physics of the Chinese Academy of Sciences, provides important clues to the spin-down mechanism and the magnetic field structure of the pulsar, as well as the physical properties of the PWN. The results were published in Nature Astronomy.

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 large scales.

Spektrum-Röntgen-Gamma, a long-delayed and much-modified X-ray astronomy package carrying the EROSITA telescope, launched successfully on Saturday.
If giant planets in other star systems lose their moons, the freed objects could become “ploonets,” and current telescopes may be able to find them.

When you look through your viewfinder and things seem a little bit blurry or lacking definition, it’s probably because you are using an “el cheapo” lens.
