Hubblecast 131 Special: Showcase of Hubble's 30th Anniversary Artistic Creations

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.

Hubblecast 130 Light: Hubble Studies the Earth during a Total Lunar Eclipse

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.

Hubblecast 121: What can we learn from exoplanet transits?

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.

Hubblecast 116: Henrietta Leavitt — ahead of her time

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.

Hubblecast 115 Light: Triangulum Galaxy in unrivalled detail

Hubblecast 114: How does Hubble orientate itself in space?

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.

Hubblecast 112 Light: Mars and Saturn

Mars and Saturn are among the most popular planets. This new episode of the Hubblecast presents the images Hubble took of these planets in summer 2018.

Hubblecast 111: Hubble sees `Oumuamua getting a boost

Astronomers have found that ‘Oumuamua, the first interstellar object discovered in the Solar System, is moving away from the Sun faster than expected. Using data from the NASA/ESA Hubble Space Telescope, in cooperation with ground-based telescopes, a team of researchers concluded that ‘Oumuamua is most likely outgassing — suggesting that this enigmatic interstellar nomad is a peculiar comet rather than an asteroid.

Hubblecast 110 Light: New test of Einstein’s general relativity

An international team of astronomers using Hubble has made the most precise test of general relativity yet outside our Milky Way.

Hubblecast 109: Diving into the Lagoon Nebula

On 24 April 1990, Hubble was launched into space. To celebrate its 28th year in orbit, some of Hubble’s precious observation time was used to observe the colourful Lagoon Nebula. One of only two star-forming nebulae visible to the unaided eye, this spectacular stellar nursery is not quite the tranquil landscape its name suggests.

Hubblecast 108 Light: Hubble finds most distant star

Astronomers have used Hubble to make an incredible discovery — they have observed the most distant star ever seen. The bright blue star existed only 4.4 billion years after the Big Bang. This incredible distant star allows astronomers to learn more about the formation and evolution of stars in the early Universe.

Hubblecast 107: Decoding the colours of NGC 3344

Our eyes detect only visible light, but on board Hubble are a variety of instruments that together detect many different wavelengths of light. This means that Hubble is able to observe galaxies over a wide range of wavelengths to reveal features that would otherwise remain invisible to our eyes.

Hubblecast 106 Light: Flying through the Orion Nebula

This visualisation takes the viewer on a breathtaking flight through the Orion Nebula, a nearby star-forming region. The video has been produced using scientific imagery and data from the NASA/ESA Hubble Space Telescope.

Hubblecast 104: Illustrating Hubble’s discoveries

Hubble is best known for its stunning images and amazing discoveries. But sometimes the discoveries do not come hand-in-hand with a breathtaking view of the Universe. Raise the curtains for the artists creating impressions of the cosmos! In this Hubblecast we learn how artist’s impressions are made and how realistic they are.

Hubblecast 103: Hubble observes source of gravitational waves for the first time

Astronomers using the NASA/ESA Hubble Space Telescope have observed a visible counterpart to gravitational waves for the first time: a kilonova from merging neutron stars.

Hubblecast 102: Taking the fingerprints of exoplanets

The atmosphere of an exoplanet can reveal a wealth of information, such as the planet’s temperature, its air pressure, and whether it is suitable for life. However, studying exoplanet atmospheres is one of the most challenging tasks in modern astronomy — and a challenge for Hubble too. This new episode of the Hubblecast describes how exoplanet atmospheres are analysed and what makes it such a challenge.

Hubblecast 100: Best of Hubblecast

Throughout its 27-year history, Hubble has seen enough of the Universe to fill 100 episodes of the Hubblecast — 10 hours worth! These episodes have captured the science, culture, trials, and successes of Hubble, ranging from its spectacular images to its cutting-edge discoveries to its impact on society.
