As we approach the 25th anniversary of the Hubble Space Telescope launching into space, we will be taking time to recognize the man who the famous telescope is named after: Edwin Hubble. 

Edwin Hubble is most widely known for being the astronomer that observed and detected the cepheid variable inside M31 The Great Nebula in Andromeda (now known as the Andromeda Galaxy), which was the evidence needed to show that the Universe we reside in is not a static one, but was expanding. 

These observations were made at the Mount Wilson Observatory in the 1920s and heralded a new way for humanity to understand the Universe. 

Please join +Tony Darnell, Dr.+Carol Christian and +Scott Lewis, who will be on location at the Carnegie Observatories office in Pasadena Calfornia, with Dr. John Mulchaey the acting director of the Carnegie Observatories as well as Nicholas (Nik) Arkimovich, a senior docent at the Mount Wilson Observatory. Together, they will bring fascinating insights into who Edwin Hubble was, as well as his remarkable achievements in astronomy.

The nebula Gum 29 is a star-forming region about 20,00 light-years away in the constellation Carina. At the core of the nebula is a cluster of several thousand stars called Westerlund 2. These newborn stars are approximately 2 million years old, and their light illuminates, heats, and erodes the surrounding gas. The Hubble image, utilizing both visible and infrared light observations, was released in celebration of the telescope’s 25th anniversary.

This visualization provides a three-dimensional perspective on the nebula and star cluster. The flight traverses the foreground stars and approaches the lower left rim of the nebula. Passing through the wispy darker clouds on the near side, the journey reveals bright gas illuminated by the intense radiation of the newly formed star cluster. Within the nebula, several pillars of dark, dense gas are being shaped by the energetic light and strong stellar winds from the brilliant cluster of thousands of stars. Note that the visualization is intended only as a scientifically reasonable interpretation and that distances within the model are significantly compressed.

With about a million observations under its belt during its 25 years of service, some of the Hubble Space Telescope’s most memorable images have been of the vastness of space and the early days of the universe. These “deep-field” images actually improved over the years because shuttle astronauts were able to upgrade the observatory. This episode, entitled “The Incredible Time Machine” shows us how Hubble has been able to give us a glimpse of a cosmos in its formative years.

Backyard stargazers get a monthly guide to the northern hemisphere’s skywatching events with “Tonight’s Sky.” In May, the Eta Aquarid meteor shower streaks through the sky, and face-on spiral galaxy M51 makes an appearance.

“Tonight’s Sky” is produced by HubbleSite.org, online home of the Hubble Space Telescope. This is a recurring show, and you can find more episodes — and other astronomy videos — at HubbleSite.org.

With images like the eXtreme Deep Field, we’ve seen how the +Hubble Space Telescope is used to observe remarkable distances in our Universe, approaching moments after the Universe ceased to be opaque. Astronomers have done it again, detecting and measuring the distance to some of the earliest objects in our Universe!

Since light has a finite speed limit, we know that the further back we look, we are also looking further back in _time_ as well. In a joint effort between HST, The Spitzer Space Telescope and the +W. M. Keck Observatory in Mauna Kea, Hawai’i, astronomers have observed light from a galaxy that left over 13 billion years ago! Due to the fact that the Universe is expanding at an accelerated rate, researchers measure the “red-shifting” of light of distant objects in order to see how much the light has stretched as space-time itself is stretched. However the further back we go, the fainter the objects are and make this form of spectroscopy extremely difficult to utilize. 

So how did astronomers measure this distant object? Find out in this week’s #HubbleHangout! Join your hosts +Tony Darnell, Dr.+Carol Christian and +Scott Lewis as they discuss the findings published in _Science_ with authors Dr. Pascal Oesch and Dr. Garth Illingworth. 

As always, you’ll be able to ask questions and make comments using the Q&A App, post comments here in the event and on +YouTube, as well as engage in the discussion on Twitter using the hash tag #HubbleHangout

Using NASA’s +Hubble Space Telescope, astronomers have captured for the first time snapshots of fledgling white dwarf stars beginning their slow-paced, 40-million-year migration from the crowded center of an ancient star cluster to the less populated suburbs.

White dwarfs are the burned-out relics of stars that rapidly lose mass, cool down, and shut off their nuclear furnaces. As these glowing carcasses age and shed weight, their orbits begin to expand outward from the star cluster’s packed downtown. This migration is caused by a gravitational tussle among stars inside the cluster. Globular star clusters sort out stars according to their mass, governed by a gravitational billiard-ball game where lower mass stars rob momentum from more massive stars. The result is that heavier stars slow down and sink to the cluster’s core, while lighter stars pick up speed and move across the cluster to the edge. This process is known as “mass segregation.” Until these Hubble observations, astronomers had never definitively seen the dynamical conveyor belt in action.

Astronomers used Hubble to watch the white-dwarf exodus in the globular star cluster 47 Tucanae, a dense swarm of hundreds of thousands of stars in our Milky Way galaxy. The cluster resides 16,700 light-years away in the southern constellation Tucana.

Please join your hosts +Tony Darnell, Dr.+Carol Christian, and +Scott Lewis as they explore this amazing migration of white dwarfs in ancient star clusters.
