Astronomers probe a mini-Neptune’s atmosphere
Exoplanet Gliese 3470 b fits nicely in size between our solar system’s Earth and planet Neptune. Known as a “mini-Neptune,” it likely has a rocky core beneath a deep, crushing, hydrogen-helium atmosphere. The analysis of its atmosphere is a first for one of these mid-sized worlds.

Image: Hubble spots a stunning spiral
Galaxies come in many shapes and sizes. One of the key galaxy types we see in the universe is the spiral galaxy, as demonstrated in an especially beautiful way by the subject of this Hubble Space Telescope image, NGC 2985. NGC 2985 lies over 70 million light-years from the solar system in the constellation of Ursa Major (the Great Bear). Source:…
Universe expansion rate mystery deepens
A new attempt to calculate how fast the universe is expanding has thrown up more questions than answers. Known as the Hubble Constant, the expansion r… Source: https://www.unexplained-mysteries.com/news/329135/universe-expansion-rate-mystery-deepens…
New measurement of universe’s expansion rate is ‘stuck in the middle’
A team of collaborators from Carnegie and the University of Chicago used red giant stars that were observed by the Hubble Space Telescope to make an entirely new measurement of how fast the universe is expanding, throwing their hats into the ring of a hotly contested debate. Their result—which falls squarely between the two previous, competing values—will be published in the…
New Hubble constant measurement adds to mystery of universe’s expansion rate
Astronomers have made a new measurement of how fast the universe is expanding, using an entirely different kind of star than previous endeavors. The revised measurement, which comes from NASA’s Hubble Space Telescope, falls in the center of a hotly debated question in astrophysics that may lead to a new interpretation of the universe’s fundamental properties.

Image: Hubble peers at galactic cherry blossoms
The galaxy NGC 1156 resembles a delicate cherry blossom tree flowering in springtime in this Hubble image. The many bright “blooms” within the galaxy are in fact stellar nurseries—regions where new stars are springing to life. Energetic light emitted by newborn stars in these regions streams outwards and encounters nearby pockets of hydrogen gas, causing the gas to glow with a characteristic…

Today in 2015: New Horizons at Pluto
The small, fast-moving New Horizons spacecraft is likely to be the only Pluto mission in the lifetimes of many of us. It changed forever the way we on Earth perceive this outermost world and its moons. Source: https://earthsky.org/space/july-4-2015-new-horizons-at-pluto…
Hubble discovers mysterious black hole disc
Astronomers using the NASA/ESA Hubble Space Telescope have observed an unexpected thin disc of material encircling a supermassive black hole at the heart of the spiral galaxy NGC 3147, located 130 million light-years away. Source: https://phys.org/news/2019-07-hubble-mysterious-black-hole-disc.html…
