Hubble Glimpses Faint Galaxy.

Fires in South America generated smoke that continues to create a long plume east into the Atlantic Ocean. Fires over western Brazil were generating aerosols at a level 2.0 on the index. Higher aerosol concentrations, as high as 4.0 were seen off the southeastern coast of Brazil as a result of the fires in the region.

The stunning radio image obtained by MeerKAT shows the central portions of the Milky Way galaxy. Its plane, marked by a series of bright features, runs horizontally through the image, while the newly discovered radio bubbles extend vertically above and below.

MIT scientists have captured the “ringing” of a newly-formed black hole, in the form of gravitational waves, depicted in this artist’s illustration.

Hubble Finds Water Vapor on Habitable-Zone Exoplanet for the First Time

This artist’s impression shows the planet K2-18b, its host star and an accompanying planet in this system. K2-18b is now the only super-Earth exoplanet known to host both water and temperatures that could support life. UCL researchers used archive data from 2016 and 2017 captured by the NASA/ESA Hubble Space Telescope and developed open-source algorithms to analyze the starlight filtered through K2-18b’s atmosphere. The results revealed the molecular signature of water vapor, also indicating the presence of hydrogen and helium in the planet’s atmosphere.
