Mars is bombarded by more meteorites than previously thought

An artist impression of a Fast Radio Burst (FRB) reaching Earth. The colors represent the burst arriving at different radio wavelengths, with long wavelengths (red) arriving several seconds after short wavelengths (blue). This delay is called dispersion and occurs when radio waves travel through cosmic plasma.

Mysterious Cloverleaf ‘odd radio circle’ could be a merger of a dozen galaxies

TIC365102760 b, shown in this artist’s concept, is nicknamed Phoenix because of its ability to be very near a red giant star and yet survive the intense radiation. Credit: Roberto Molar Candanosa/Johns Hopkins University.

Neptune-like planet ‘Phoenix’ baffles astronomers with its atmosphere

Frost (colored blue) coats the top of Olympus Mons, the tallest volcano in our solar system. This image was shot by ESA’s Mars Express orbiter at 7:20 A.M. local martian time. The mountain’s right side is illuminated by the rising Sun in the east. Credit: ESA/DLR/FU Berlin.

Around a star in our Milky Way galaxy, astronomers have discovered an extremely low-density planet that is as light as cotton candy. The new planet, named WASP-193b, appears to dwarf Jupiter in size, yet it is a fraction of its density. Credit: K. Ivanov/MIT.
