A team of astronomers have discovered a planet closer and younger than any other Earth-sized world yet identified. It’s a remarkably hot world whose proximity to our own planet and to a star like our sun mark it as a unique opportunity to study how planets evolve.The new planet was described in a new study published this week by The Astronomical Journal.

These are Hubble Space Telescope images of two massive clusters of galaxies. The artificially added blue color is translated from Hubble data that captured a phenomenon called intracluster light. This extremely faint glow traces a smooth distribution of light from wandering stars scattered across the cluster. Billions of years ago, the stars were shed from their parent galaxies and now drift through intergalactic space alone.

Webb's first look at Neptune is certainly a stunner! We're getting the clearest view of Neptune's rings in decades. The faint, dustier bands have never been seen in the infrared like we see now. At near-infrared wavelengths, Neptune's methane gas so strongly absorbs red and infrared light that the planet is quite dark, except where high-altitude clouds are present. These methane-ice clouds are prominent as bright streaks and spots in Webb's view.

NASA’s James Webb Space Telescope presents a new perspective on 30 Doradus, or the Tarantula Nebula, a region well-known to astronomers studying star formation. Its nickname once came from its resemblance to the spider itself, but in Webb’s view the overall region takes on the appearance of a tarantula’s home—a burrow lined with its own spun silk. The Tarantula Nebula shelters thousands of young and still-forming stars, many revealed by Webb for the first time.

NASA’s Webb Reveals Cosmic Cliffs, Glittering Landscape of Star Birth
Space Telescope Science Institute (STScI)

The seemingly three-dimensional “Cosmic Cliffs” showcases Webb’s capabilities to peer through obscuring dust and shed new light on how stars form. Webb reveals emerging stellar nurseries and individual stars that are completely hidden in visible-light pictures. This landscape of “mountains” and “valleys” is actually the edge of a nearby stellar nursery called NGC 3324 at the northwest corner of the Carina Nebula. So-called mountains — some towering about 7 light-years high — are speckled with glittering, young stars imaged in infrared light. A cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located above the area shown in this image. The blistering, ultraviolet radiation from these stars is sculpting the nebula’s wall by slowly eroding it away. Dramatic pillars rise above the glowing wall of gas, resisting this radiation. The “steam” that appears to rise from the celestial “mountains” is

Comet 67P’s Abundant Oxygen More of an Illusion, New Study Suggests
Johns Hopkins University Applied Physics Laboratory

When the European Space Agency’s Rosetta spacecraft discovered abundant molecular oxygen bursting from comet 67P/Churyumov-Gerasimenko (67P) in 2015, it puzzled scientists. They had never seen a comet emit oxygen, let alone in such abundance. But most alarming were the deeper implications: that researchers had to account for so much oxygen, which meant reconsidering everything they thought they already knew about the chemistry of the early solar system and how it formed. A new analysis, however, led by planetary scientist Adrienn Luspay-Kuti at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, shows Rosetta’s discovery may not be as strange as scientists first imagined.
