Yes! Hubble is Back in Operation

Since it was first launched into space in 1990, the Hubble Space Telescope has become something of a household name. Over the course of its almost thirty years of service, Hubble has established a reputation as one of NASA’s Great Observatories, giving astronomers the ability to look farther into the cosmic field than ever before and learn new and fascinating things about our Universe.

During April 2017 Jupiter is in opposition: it is at its closest to Earth and the hemisphere facing Earth is fully illuminated by the Sun. The NASA/ESA Hubble Space Telescope used this special configuration to capture an image of what is by far the largest planet in the Solar System. This image adds to many others made in the past, and together they allow astronomers to study changes in the atmosphere of the gas giant.

Hubble breaks cosmic distance record

By pushing the NASA/ESA Hubble Space Telescope to its limits astronomers have shattered the cosmic distance record by measuring the distance to the most remote galaxy ever seen in the Universe. This galaxy existed just 400 million years after the Big Bang and provides new insights into the first generation of galaxies. This is the first time that the distance of an object so far away has been measured from its spectrum, which makes the measurement extremely reliable. The results will be published in the Astrophysical Journal.
