On 24 April 2020, the NASA/ESA Hubble Space Telescope celebraetd its 30th anniversary. ESA/Hubble invited the general public to submit Hubble-themed artistic creations to celebrate this special milestone. Submissions received included drawings, paintings, sculptures, music, and poetry that were all inspired by the Hubble Space Telescope. This Hubblecast features a variety of the visual creations received.

Taking advantage of a total lunar eclipse in January 2019, astronomers using the NASA/ESA Hubble Space Telescope have measured the amount of ozone in Earth’s atmosphere. This method serves as a proxy for how they will observe Earth-like planets around other stars in search of life.

This new Hubblecast episode explores what we can learn through the transits of exoplanets. It also tells us what we have learned from these transits with the help of Hubble and which discoveries we can expect with the NASA/ESA/CSA James Webb Space Telescope.

Born in 1868, Henrietta Leavitt was an astronomer ahead of her time, whose work helped to revolutionise our understanding of the Universe. While working at Harvard Observatory, she began to study stars of fluctuating brightness. She made a crucial observation about these objects, which gave astronomers a new way to measure distances, ultimately leading to such impactful discoveries as the expansion of the Universe.

This new Hubblecast episode takes a detailed look into the refined Pointing Control System that allows Hubble to keep its gaze into the Universe firm and steady.
