Horse of a Different Color: Hubble’s Universe Unfiltered (Show 20)

The Horsehead Nebula is a striking, dark gas cloud just below Orion’s belt. It is a favorite of both professional and amateur astronomers. However, as a dark nebula, most of its true structure is hidden from visible light observations. To celebrate the 23rd anniversary of the Hubble Space Telescope, we revealed the considerable detail of that unseen nebular structure via an infrared portrait. The result is even more striking, and something one just doesn’t see very often: a veritable astronomical horse of a different color.

Planet Discoveries Revisited: Hubble’s Universe Unfiltered (Show 19)

The field of extrasolar planets has exploded over the last couple decades, providing an entirely new suite of information on planetary systems in general and perspective on our own solar system in particular. One of the most exciting advances came when astronomers were at last able to see a few of these planets directly. Even those who maintain “I’ll believe it when I see it” now have visual proof that our solar system is not alone in the universe. However, science advances rapidly, and the discoveries announced only a few years ago are already ripe for an update. Revisiting three direct detections provides confirmation, archival data, and some spirited scientific discussion.

The Future of Space Astronomy: Hubble’s Universe Unfiltered (Show 18)

The Hubble Space Telescope has made amazing astronomical discoveries for 23 years. It still has a good number of years left, but without the Space Shuttle, servicing missions are no longer possible. The natural question is “what’s next?”

Clash of the Titans: Hubble’s Universe Unfiltered (Show 17)

Astronomers have known for decades that our Milky Way Galaxy and the neighboring Andromeda Galaxy are approaching each other. What we haven’t known is just how close the encounter will be. Recent Hubble measurements have been able to pin down the trajectory with a smashing conclusion: in about four billion years the two galaxies will crash together in a nearly head-on collision. Further, the spiral galaxies will have completely merged and transformed to create a single elliptical galaxy around six billion years in the future.

Changing Views of Pluto: Hubble’s Universe Unfiltered (Show 15)

Pluto’s classification as a “dwarf planet” came as a shock to some, but in reality our understanding of Pluto has always been in flux. Pluto is a tiny, distant, icy object, difficult to see even with Hubble’s vision. Join a Hubble astrophysicist as we explore our history with Pluto, from its discovery to the excitement over the upcoming visit by the New Horizons space probe, in Hubble’s Universe Unfiltered.

A Runaway Star: Hubble’s Universe Unfiltered (Show 14)

An enormous star is on the lam, fleeing its home at a quarter of a million miles per hour. The star, 90 times as massive as the Sun, may have traveled 375 light years from its original locale, the giant star cluster R136 in the 30 Doradus Nebula. How did it get away? A Hubble astrophysicist explores the discovery in the ongoing series, “Hubble’s Universe Unfiltered.”

An Un-peculiar Trio of Galaxies?: Hubble’s Universe Unfiltered (Show 10)

In 2009, HubbleSite let the public vote on an object to be observed by the Hubble Telescope. The world picked Arp 274, a trio of galaxies 400 million light-years away in the constellation Virgo. The galaxies appeared at first to be overlapping, but may actually be distant from one another.

In the Service of Science: Hubble’s Universe Unfiltered (Show 9)

In May 2009, seven astronauts aboard Space Shuttle Atlantis visited the Hubble Space Telescope for a final servicing mission. The drama of a shuttle flight with ambitious and challenging spacewalks that refreshed, repaired, and renewed astronomy’s most beloved telescope captured the attention of the world.

Goodnight Moon: Hubble’s Universe Unfiltered (Show 8)

Occultation occurs when one celestial body — for instance, a moon or a planet — aligns with another. Striking images of occultation give us an unusual glimpse of the traffic in our cosmic backyard.

Eye Spy a Planet: Hubble’s Universe Unfiltered (Show 7)

In 2008, Hubble released the first visible-light picture of a planet around another star. Planets around distant stars are extremely difficult to visualize — astronomers usually find them by observing the dimming of light as a planet passes in front of a star, or the wobble of the star as its tugged by the planet’s gravity.

Through a Lens, Brightly: Hubble’s Universe Unfiltered (Show 5)

Matter warps the space around it. The more matter there is, the stronger the warp. For really strong distortions of space-time, like black holes, the warping acts like a lens. Such gravitational lenses have been found, and astronomers can use them to study very distant and very faint galaxies.

Jupiter Gets the Measles: Hubble’s Universe Unfiltered (Show 4)

Jupiter’s Great Red Spot, a whirling storm on the gas giant planet’s surface, has been one of the planet’s most recognizable features for centuries. But in 2006 and 2008, Jupiter’s Great Red Spot was joined by two companions, smaller red spot storms.

Hubble Servicing Delayed: Hubble’s Universe Unfiltered (Show 3)

In September 2008, Hubble was two weeks away from a servicing mission when an electrical problem shut down much of the telescope. Intense work and effort has resulted in a replacement part to fix the problem. The servicing mission took place in 2009 and was entirely successful, and Hubble is expected to continue for many more years.

Interacting Galaxies Galore: Hubble’s Universe Unfiltered (Show 1)

Hubble celebrated its 18th anniversary in 2008 by releasing a huge image gallery of interacting galaxies. Such galaxies pass close enough to each other that their mutual gravity can stretch and distort their shapes. Eventually, interacting galaxies merge together to form a single larger galaxy. However, since these interactions can take billions of years, how do we study them?
