NASA’s Robotic Refueling Mission 3 (RRM3) completed an initial set of tool operations, bringing the idea of using water ice or methane from other worlds as fuel for spacecraft one step closer to reality. The ability to store and transfer cryogens (super-cold hydrogen, oxygen and methane) will help spacecraft journey father into our solar system and beyond.

Although it looks more like an entity seen through a microscope than a telescope, this rounded object, named NGC 2022, is certainly not algae or tiny, blobby jellyfish. Instead, it is a vast orb of gas in space, cast off by an aging star. The star is visible in the orb's center, shining through the gases it formerly held onto for most of its stellar life.

New interior models of Jupiter based on data gathered by NASA’s Juno mission suggested that the giant gas planet might not have a small compact core but rather a diluted, “fuzzy” one. Now, an international team with researchers of the University of Zürich and the NCCR PlanetS has found an explanation for this surprising Juno result. A giant impact occurring shortly after Jupiter’s formation may have disrupted and diluted its original compact core.

On July 24, 1969, Apollo 11 command module Columbia splashed down in the Pacific, fulfilling President Kennedy's goal to land a man on the Moon and return him safely to Earth. Among the mission's many firsts was the acquisition and return of the first samples from another celestial body. Findings based on the 47 pounds (21.5 kilograms) of lunar rock and soil rewrotethe textbooks on both the Moon and solar system, and the samples are still being studied today by researchers using new and more sensitive instruments.

Harsh ultraviolet radiation flares from red suns, once thought to destroy surface life on planets, might help uncover hidden biospheres. Their radiation could trigger a protective glow from life on exoplanets called biofluorescence, according to new Cornell research.

The faint glow of a directly imaged planet will one day have much to tell us, once we’ve acquired equipment like the next generation of extremely large telescopes (ELTs), with their apertures measuring in the tens of meters. Discovering the makeup of planetary atmospheres is an obvious deep dive for biosignatures, but there is another. Biofluorescence, a kind of reflective glow from life under stress, could be detectable in some conditions at astronomical distances.

For many years, astronomers have looked forward to a coming revolution in ground-based astronomy: going from the current generation of 8-to-10 meter telescopes to the next generation of 30-meter class telescopes. Approximately a decade ago, a variety of partnerships selected their preferred sites, instruments to build, and facilities to construct. Now, in 2019, two of them are right on track, while one — the Thirty Meter Telescope (TMT) in Hawaii — is years behind. The overwhelming majority of astronomers recognize that the preferred site for TMT, atop Hawaii’s Mauna Kea, would be the technically superior location to build it. But doing so would ignore the objections of many citizens whose concerns and values have been marginalized for over a century. As astronomers prepare for a field-defining choice, here’s what everyone should know.

So much rides on the successful launch and deployment of the James Webb Space Telescope that I never want to take its capabilities for granted. But assuming that we do see JWST safely orbiting the L2 Lagrange point, the massive instrument will stay in alignment with Earth as it moves around the Sun. allowing its sunshield to protect it from sunlight and solar heating.
