Backyard stargazers get a monthly guide to the northern hemisphere’s skywatching events with “Tonight’s Sky.” Venus and Mars huddle together on cold February nights, and star clusters are prominent in the month’s constellations.

“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.

Europa, Callisto, and Io, three of Jupiter’s four largest moons, can commonly be seen transiting the face of the giant planet and casting shadows onto its cloud tops. However, seeing three moons transiting the face of Jupiter at the same time is rare, occurring only once or twice a decade.

On Janurary 24th, 2015, the +Hubble Space Telescope  captured a rare look at three of Jupiter’s largest moons zipping across the banded face of the gas giant planet.

From Cosmic Birth to Living Earth: The Next Great Space Telescope Beyond JWST

Are we alone? How did we get here? These are perennial questions that pique our curiosity and probe to the very heart of our existence. While our historical attempts to address these questions have progressed from the philosophical toward the scientific, astronomy is currently in a golden age that promises to get even brighter. New technologies, new telescopes, and new discoveries will bring forth exciting prospects for broad advances in understanding the cosmos and the life within it over the next two decades.

Hosted by Dr. Frank Summers. Recorded live on February 3, 2015 at the Space Telescope Science Institute in Baltimore, MD, USA

This year marks 25 years of amazing images and science from the Hubble Space Telescope.  To celebrate, we’ve assemble 25 images that represent both the beauty of the universe captured by Hubble and the important science realized by this wonderful telescope orbiting over our heads.

Please join +Tony Darnell, Dr +Carol Christian and +Scott Lewis  as they discuss these images.

Beta Pictoris remains the only directly imaged debris disk that has a giant planet (discovered in 2009) with an orbital period short enough (estimated to be between 18 and 22 years) that astronomers can see large motion in just a few years. This allows scientists to study how the Beta Pictoris disk is distorted by the presence of a massive planet embedded within the disk.

Please join +Tony Darnell, Dr. +Carol Christian and +Scott Lewis as they discuss new visible-light Hubble images that traces the disk in closer to the star to within about 650 million miles of the star with the astronomers who made the observations.

The Hubble Space Telescope is named after one of the preeminent astronomers of the last century, Edwin Hubble. Among his notable discoveries is that the universe we live in is both enormous and expanding. This episode takes us on a journey through the life and times of the person whose name graces one of the most significant scientific instruments ever built.

Hypergiant stars are among the largest and most luminous in the universe and when they die, they create an enormous explosion, known as hypernovae.  Astronomers using the +Hubble Space Telescope have observed several supernovae in galaxies NGC 266 and NGC 7714 and believe them to be caused by the deaths of these hypergiant stars.

Please join +Tony Darnell Dr. +Carol Christian and +Scott Lewis as they explore the realm of hypergiant stars and discuss recent Hubble observations of SN 2005gl and others.

Astronomers using NASA’s  Hubble Space Telescope have spotted for the first time a distant supernova split into four images. The multiple images of the exploding star are caused by the powerful gravity of a foreground elliptical galaxy embedded in a massive cluster of galaxies.
This unique observation will help astronomers refine their estimates of the amount and distribution of dark matter in the lensing galaxy and cluster. Dark matter cannot be seen directly but is believed to make up most of the universe’s mass.

These observations were taken as part of the Frontier Fields Survey.

Please join +Tony Darnell Dr.+Carol Christian and +Scott Lewis as they discuss these exciting observations with members of the Frontier Fields Team.
