Scientists were able to measure the cosmic optical background (COB) thanks to the data from New Horizons space probe at the edge of the Solar system. The light is significantly brighter than what light from known sources can explain. According to a new study led Teresa Symons it is two to three times brighter.
Lyman Alpha is a specific line in electromagnetic spectrum, which is emitted when an electron jumps from 2nd orbital state to the 1st one. In inner solar system the Lyman-Alpha radiation from the Sun is prevalent, but beyond the orbit of Pluto, the galactic variety comes to light.
Binary star TOI 1338 has at least two exoplanets orbiting it. Astronomers led by Matthew Standing discovered the second one using radial velocity method and data from observatories La Silla and VLT. Exoplanet TOI 1338 c is the first one detected solely by the radial velocity method and the system TOI 1338 is now the second known to have multiple exoplanets orbiting more than one star.
New observations revealed that the two stars in the nearby system LP 413-53 are separated only by 0.01 AU (that is 1 % of distance between Earth and the Sun). This record-breaking distance means the stars orbit each other in mere 20.5 hours.
