In this new Hubblecast episode, Dr. J guides us through the second chapter of Eyes on the Skies, the International Astronomical Union's official movie celebrating the telescope on its 400th anniversary in 2009.

As the summer comes to a close, take a moment to enjoy some of the best scenes from Earth, the solar system and beyond.

The Hubble Space Telescope has solved a long-standing puzzle by resolving giant but delicate filaments shaped by a strong magnetic field around the active galaxy NGC 1275. It is the most striking example so far of the influence of the immense tentacles of extragalactic magnetic fields.

America's first woman astronaut discusses how JPL instruments and missions have helped revolutionize what we know about Earth.

Summer is here so it's the perfect season to talk about the sun.

The sun will soon set on the Ulysses solar mission, which forever changed the way scientists view the sun and its affect on space.

Animation and mission control video from Mars Phoenix landing day May 25, 2008.

This video includes highlights from the entry, descent and landing phase as Mars Phoenix Lander touched down on the Red Planet on May 25, 2008.

Scientists plan intriguing research, once Phoenix lands safely on Mars.

Cassini completes the final Titan flybys of its original Saturn tour and prepares for a two-year extension.

A new satellite mission will help monitor Earth's changing climate and improve weather forecasting.

Catch up on mission news with this 20-minute overview. From Saturn to Mars, and Earth to the stars, JPL has it covered!

Get ready to gaze at galaxies through your telescope. Then compare your views to those taken in infrared by the Spitzer Space Telescope.

One of the big mysteries in astronomy is how galaxies grow and evolve over time. Collisions between galaxies are thought to be key events that shape their development. A stunning collection of 59 new images of colliding galaxies has been released to mark the 18th anniversary of the NASA/ESA Hubble Space Telescope. They give us a unique insight into how galaxies collide to form larger galaxies.

Scientists and educators teach students about climate change and its impact on Earth.

For astronomers, Omega Centauri has been an outcast amongst globular clusters for a long time. A new result obtained by the NASA/ESA Hubble Space Telescope and the Gemini Observatory provides a surprising explanation for Omega Centauri's peculiarities.

It will be a real nail-biter on May 25, 2008, for engineers, as the Phoenix spacecraft performs a series of challenging maneuvers right before it lands on Mars. Phoenix will land on the north polar region of Mars.

Cassini tour designers worked at breakneck speed on plans for the spacecraft's extended stay in the Saturn system.

The NASA/ESA Hubble Space Telescope has made the first detection ever of an organic molecule in a planet orbiting another star. This breakthrough is an important step in eventually identifying signs of life on a planet outside our Solar System.

On March 12, NASA's Cassini spacecraft will make its closest flyby yet to Saturn's moon Enceladus. Cassini's goal: To scoop up samples of water-ice particles and gas spewing from Old-Faithful-like geysers.

The NASA/ESA Hubble Space Telescope has captured a new image of the galaxy NGC 1132 which is most likely to be a cosmic fossil - the aftermath of an enormous multi-galactic pile-up, where the carnage of collision after collision has built up a brilliant but fuzzy giant elliptical galaxy far outshining typical galaxies.

2007 was a year of scientific surprises and major milestones for JPL missions studying Earth, our solar system and distant galaxies.

Where's a great place to look for life in our solar system beyond Earth? Jupiter's moon, Europa, with its warm salty ocean, might be a good place to start.

Mars and Earth are at their closest this month so now is your best chance to see our planetary neighbor.

Using the NASA/ESA Hubble Space Telescope, astronomers have found the first clear evidence of high altitude haze or clouds in the atmosphere of an extrasolar planet. This discovery reveals a deeper understanding of the class of giant planets that astronomers call hot Jupiters.

The galaxy Messier 74 lies at a distance of over 30 million light years. In this latest image from the NASA/ESA Hubble Space Telescope the enormous swirls of this stunning spiral galaxy arc across space, adorned with glowing pink regions of hydrogen gas and lit by the pale blue light of millions of newly formed stars.

We live in a Universe of unimaginable scale and almost incomprehensible beauty. How is the light from the Universe transformed into the images that have inspired generations by making the Universe come to life?

This month you'll have great views of a red planet and a red star. Plus, find out when the Mars rovers are facing Earth.

Scientists recently watched on the edge of their seats as close-up images from Saturn's odd moon Iapetus beamed back to Earth. Relive the adventure, as they see photos of the odd black-and-white moon, and try to figure out what caused the unusual color patterns.

Pull out your telescope to see Saturn's black-and-white moon Iapetus. And there's something for everyone on Halloween: Jupiter for the early crowd and Mars for the late-night trick or treaters.

The NASA/ESA Hubble Space Telescope has captured a spectacular image of NGC 3603, a giant nebula hosting one of the most prominent massive young clusters in the Milky Way. This is a splendid location for continued studies of stellar birth in star forming regions.

The change over the arctic sea ice is stunning. Between 2005 and this winter, thick ice has been reduced by about the size of Californian and Texas combined. Scientists are tracking the causes.

The Mars Reconnaissance Orbiter is providing unprecedented views as it studies the red planet.

On Saturday August 4, the Mars Phoenix spacecraft launched from Cape Canaveral, Florida.

The Dawn mission will go to Vesta and Ceres, the two most massive bodies in the asteroid belt. T
