Hubble and Gaia Team Up to Fuel Cosmic Conundrum

Space Telescope Science Institute (STScI)

Using the Hubble and Gaia space observatories, astronomers have made the most precise measurements to date of the expansion of space, which may suggest reworking our understanding of the physics of the universe.

NASA’s Webb Space Telescope to Inspect Atmospheres of Gas Giant Exoplanets

Space Telescope Science Institute (STScI)

In April 2018, NASA launched the Transiting Exoplanet Survey Satellite (TESS). Its main goal is to locate Earth-sized planets and larger “super-Earths” orbiting nearby stars for further study. One of the most powerful tools that will examine the atmospheres of some planets that TESS discovers will be NASA’s James Webb Space Telescope. Since observing small exoplanets with thin atmospheres like Earth will be challenging for Webb, astronomers will target easier, gas giant exoplanets first.

Astronomers Release Most Complete Ultraviolet-Light Survey of Nearby Galaxies

Space Telescope Science Institute (STScI)

Using the Hubble Space Telescope's unparalleled sharpness and spectral range, an international research team has created the most comprehensive, high-resolution ultraviolet-light survey of star-forming galaxies in the local universe. The LEGUS data provide detailed information on 39 million young, massive stars and 8,000 star clusters, and how their environment affects their development.

Hubble Detects Helium in the Atmosphere of an Exoplanet for the First Time

Space Telescope Science Institute (STScI)

An international team of astronomers using the Hubble Space Telescope have detected helium in the atmosphere of the exoplanet WASP-107b. This is the first time this element has been detected in the atmosphere of a planet outside the solar system. The discovery demonstrates the ability to use infrared spectra to study exoplanet extended atmospheres.

Stellar Thief Is the Surviving Companion to a Supernova

Space Telescope Science Institute (STScI)

In the fading afterglow of a supernova explosion, astronomers using NASA’s Hubble Space Telescope have photographed the first image of a surviving companion to a supernova. This is the most compelling evidence that some supernovas originate in double-star systems.

NASA’s James Webb Space Telescope Could Potentially Detect the First Stars and Black Holes

Space Telescope Science Institute (STScI)

One of the key science goals of NASA’s James Webb Space Telescope is to learn about “first light,” the moment when the first stars and galaxies lit the universe. While the first galaxies will be within Webb’s reach, individual stars shine so faintly that Webb would not be able to detect them without help. That help could come in the form of natural magnification from gravitational lensing, according to a new theoretical paper.

Hubble Makes the First Precise Distance Measurement to an Ancient Globular Star Cluster

Space Telescope Science Institute (STScI)

Using NASA’s Hubble Space Telescope, astronomers were able to use the same sort of trigonometry that surveyors use to precisely measure the distance to NGC 6397, one of the closest globular clusters to Earth. The only difference is that the angles measured in Hubble’s camera are infinitesimal by earthly surveyors’ standards.

Hubble Uncovers the Farthest Star Ever Seen

Space Telescope Science Institute (STScI)

Using the Hubble Space Telescope and a quirk of nature called gravitational lensing, an international team of astronomers has found the most distant individual star ever discovered, dubbed "Icarus." This discovery provides new insight into the formation and evolution of stars in the early universe, the makeup of galaxy clusters, and the nature of dark matter.
