Hubblecast 51: Star-forming region S 106

15 December 2011: In this episode of the Hubblecast, we take a tour of the compact star-forming region Sh 2-106. Its hourglass shape is caused by the final, violent phases of a star’s formation in the middle of the gaseous nebula. This episode explains some of the science behind Hubble’s observations and brings ...

Dissecting a Black Hole's Surroundings

29 September 2011: A fleet of spacecraft including the NASA/ESA Hubble Space Telescope has shown unprecedented details in the environs of a supermassive black hole. Observations reveal huge bullets of gas being driven away from the gravitational monster and a corona of very hot gas hovering above the disc of matter that is ...

From the Distant Past to the New World

23 September 2011: A public art installation featuring Hubble observations of distant galaxies, quasars and stars is going to the USA. From the Distant Past features a laser projecting spectra from distant celestial objects onto the facades of buildings. While the green lines might appear abstract at first, they represent light, split into ...

Even low-mass galaxies can harbour supermassive black holes

16 September 2011: Using the slitless grism on the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 to probe the distant universe, astronomers have found supermassive black holes growing in surprisingly small galaxies. The findings suggest that central black holes formed at an early stage in galaxy evolution. This study is part of ...

Hubblecast 49: Supersonic jets from newborn stars

31 August 2011: In this episode of the Hubblecast, Joe Liske (aka Dr J) looks at newborn stars firing out jets of matter. These jets may cast new light on how the Sun formed 4.5 billion years ago.An international team of scientists led by astronomer Patrick Hartigan of Rice University in Houston, USA, ...

Your Chance to Ask Hubble

30 August 2011: Do you have a burning astronomy question? Now’s the time to ask. To celebrate the 50th episode of ESA’s Hubblecast series, our host, Dr Joe Liske, aka Dr J, will be answering your astronomy questions. Maybe you want to know more about black holes, supernovae, or dark matter? Or perhaps ...

Hubblecast 48: Deep observations of the Andromeda Galaxy

21 July 2011: In this episode of the Hubblecast, Joe Liske — aka Dr J — takes us on a tour of the outer reaches of the Andromeda Galaxy (Messier 31), the closest spiral galaxy to our Milky Way. Hubble’s vision is so sharp that it resolves the grey blob that’s visible to ...

Happy Anniversary, Neptune

12 July 2011: This blue ball is Neptune, the eighth and outermost planet of our Solar System [1]. The NASA/ESA Hubble Space Telescope made this picture on 25-26 June 2011 to celebrate the first anniversary of Neptune’s discovery... in Neptune years. Neptune’s leisurely journey around the Sun takes 60 190 Earth days — ...

Hubble makes its millionth observation

5 July 2011: The NASA/ESA Hubble Space Telescope has made its millionth observation since its launch 21 years ago. The telescope was used to search for the chemical signature of water in the atmosphere of planet HAT-P-7b [1], a gas giant larger than Jupiter which orbits the star HAT-P-7. Alvaro Gimenez, head of ...

Hubblecast 47: Pandora's Cluster

22 June 2011: This joint episode of the Hubblecast and ESOcast presents Abell 2744, an unusual cluster of galaxies nicknamed "Pandora’s Cluster". Looking at the galaxies, gas and dark matter in the cluster, scientists have reconstructed the series of huge collisions that created it, and have uncovered some strange phenomena never seen together ...

Hubble watches a supernova light up again

9 June 2011: In 1987, the light from an exploding star in a neighbouring galaxy, the Large Magellanic Cloud, reached Earth. Since its launch in 1990, the NASA/ESA Hubble Space Telescope has studied the wreckage of this dead star, called Supernova 1987A, and has watched it evolve. Supernova 1987A is the closest supernova ...
