This week, scientists shared discoveries of ancient species that lived and died tens of millions of years ago, providing tantalizing insights into creatures never documented until now. The colossal ancient whale, which swam the seas about 39 million years ago, likely weighed two to three times more than the blue whale. NASA/ESA/Joseph Olmsted (STScI)When the Hubble Space Telescope initially observed a young planetary system 32 light-years from Earth, it didn’t reveal any surprises. And the James Webb Space Telescope spied new details within the colorful, iconic Ring Nebula. The fruit flies in the groundbreaking study don’t typically reproduce through virgin births, also called parthenogenesis, although many animal species do.

CNN —The James Webb Space Telescope has detected water vapor around a rocky exoplanet that orbits a star located 26 light-years away from Earth. The presence of water vapor could suggest that GJ 486 b somehow has an atmosphere, despite its heat and proximity to the star. “Water vapor in an atmosphere on a hot rocky planet would represent a major breakthrough for exoplanet science. The results from the Webb data analysis pointed to water vapor being present around GJ 486 b. Future observations of the planet using different instruments on the Webb telescope could reveal additional details about the source of the water vapor.
A new study has offered a more sober explanation - that 'Oumuamua's speed-up was due to the release of hydrogen gas as the comet warmed up in the sunlight. "The key finding is that 'Oumuamua may have started as a water-rich icy planetesimal broadly similar to solar system comets. "We don't know its place of origin but it was probably traveling through interstellar space for less than 100 million years. It had a reddish color consistent with the colors of many small bodies in the solar system. A second interstellar object, the comet 2I/Borisov, was discovered visiting our solar system in 2019.
