Chandra may have first evidence of a young star devouring planet

Out of the blue, scientists have detected the destruction of a young planet or planets around a nearby star. This revelation gives an understanding...
Using two of the world’s most powerful space telescopes — NASA’s Hubble and ESA’s Gaia — astronomers have made the most precise measurements to date of the universe’s expansion rate. This is calculated by gauging the distances between nearby galaxies using special types of stars called Cepheid variables as cosmic yardsticks. By comparing their intrinsic brightness as measured by Hubble, with their apparent brightness as seen from Earth, scientists can calculate their distances. Gaia further refines this yardstick by geometrically measuring the distances to Cepheid variables within our Milky Way galaxy. This allowed astronomers to more precisely calibrate the distances to Cepheids that are seen in outside galaxies. Credits: NASA, ESA, and A. Feild (STScI)

Astronomers have made the most precise measurement to date of the universe’s expansion rate

Utilizing the power and cooperative energy of two space telescopes, astronomers have influenced the most exact estimation to date of the universe's expansion rate. The...
This is an artist's impression of the Jupiter-size extrasolar planet, HD 189733b, being eclipsed by its parent star. Astronomers using the Hubble Space Telescope have measured carbon dioxide and carbon monoxide in the planet's atmosphere. The planet is a "hot Jupiter," which is so close to its star that it completes an orbit in only 2.2 days. The planet is too hot for life as we know it. But under the right conditions, on a more Earth-like world, carbon dioxide can indicate the presence of extraterrestrial life. This observation demonstrates that chemical biotracers can be detected by space telescope observations. Credits: ESA, NASA, M. Kornmesser (ESA/Hubble), and STScI

NASA’s Webb space telescope to inspect atmospheres of gas giant exoplanets

In April 2018, NASA propelled the Transiting Exoplanet Survey Satellite (TESS). Its fundamental objective is to find Earth-sized planets and bigger "super-Earths" revolving nearby...

Hubble captures cluster of aging stars

This rich and thick smattering of stars is a massive globular cluster, a gravitationally bound gathering of stars that orbits the Milky Way. Globular...
These images show the sunlit side of Earth in 10 different wavelengths of light that fall within the infrared, visible and ultraviolet ranges; the images are representational-color, because not all of these wavelengths are visible to the human eye. Each wavelength highlights different features of the planet -- for example, the continent of Africa is visible in the lower right image, but is nearly invisible in the upper left image. These observations were obtained by NASA's Earth Polychromatic Imaging Camera (EPIC) instrument onboard the National Oceanic and Atmospheric Administration's Deep Space Climate Observatory, or DSCOVR, satellite, on Aug. 2, 2017.
