On the Trail of the Missing Galaxies: The Oldest Stars in the Neighborhood
Tom Brown, Space Telescope Science Institute

In the past decade, wide-field surveys have revealed a new class of ultra-faint dwarf galaxies orbiting the Milky Way and Andromeda. They are the least luminous, most dark-matter dominated, and least chemically-evolved galaxies known. These faint galaxies offer a new front in efforts to understand the missing satellite problem - the discrepancy that theory predicts many more satellite galaxies than the number of dwarf galaxies observed. As the best candidates for fossils from the early universe, the ultra-faint dwarfs are ideal places to test the physics of galaxy formation from that era. New data from the Keck Observatory and the Hubble Space Telescope provide evidence that reionization in the early universe suppressed star formation in the smallest seeds of galaxy formation, thus providing a possible explanation for the missing satellite problem.

It is the 50th anniversary of Star Trek and Hubble has been in orbit doing incredible science for more than half of that time. Read more about the connections between #‎Hubble and #‎StarTrek in this #‎FrontierFields post by Dr. Frank Summers

Celebrating its 50th anniversary this year, the TV series "Star Trek" has captured the public's imagination with the signature phrase, "To boldly go where no one has gone before." The Hubble Space Telescope simply orbits Earth and doesn't "boldly go" deep into space. But it looks deeper into the universe than ever before possible to explore the fabric of time and space and find the farthest objects ever seen. This is epitomized in this Hubble image that is part of its Frontier Fields program to probe the far universe. This view of a massive cluster of galaxies unveils a very cluttered-looking universe filled with galaxies near and far. Some are distorted like a funhouse mirror through a warping-of-space phenomenon first predicted by Einstein a century ago.

A team of astronomers has directly imaged the first planet ever found in a wide orbit inside a triple-star system. The orbit of such a planet had been expected to be unstable, probably resulting in the planet being quickly ejected from the system. But somehow this one survives.

The artist's impression shows a view of the HD 131399 system from the perspective of the giant planet, HD 131399Ab (lower left), orbiting in the system. The planet is about 16 million years old, making it one of the youngest exoplanets discovered to date – and one of just a handful of “directly imaged” planets. It is also one of the coldest and least massive exoplanets that have been directly imaged.

The galaxies in the early universe were much smaller than our Milky Way and churned out stars at a rapid pace. They grew larger through mergers with other dwarf galaxies to eventually build the magnificent spiral and elliptical galaxies we see around us today. But astronomers using the Hubble Space Telescope have looked at two small galaxies that were left off the star party list. For many billions of years Pisces A and Pisces B lived in a vast intergalactic wilderness that was devoid of gas, which fuels star formation. They got left out in the cold.

Better late than never. Like Rip van Winkle awakening from a long slumber, the dwarf galaxies have now ended their star-making drought and have joined the party. Astronomers estimate that less than 100 million years ago the galaxies doubled their star-formation rate. For most of the universe's history these puny galaxies dwelled in the Local Void, a region of the universe sparsely populated with galaxies. Now the galaxies have moved into a region crowded with galaxies and full of intergalactic gas. This dense environment is triggering star birth.

Si un Univers primitif est reconnu face à la multiplicité des hypothèse qui tentent d'expliquer l'origine de sa formation,l'actuel serait-il en voie de renaissance?Il est intéressant de suivre son évolution avec les spécialistes.

NASA’s Hubble Space Telescope has arguably been the quintessential symbol of scientific achievement for decades. But that notoriety has parlayed into a unique position in pop culture. Hubble, and the images of the universe it produces, has not only helped astronomers rewrite textbooks but also has permeated areas traditionally isolated from science. In this episode of the Hubble at 25 and Beyond series, we take a look at some examples of how Hubble has indeed become a household name all over the world.

Hubble is more than a science spacecraft; it’s a cultural phenomenon! Think about where you’ve seen images of the Hubble Space Telescope or Hubble images in your daily life … a textbook, mural, clothing. Snap a photo and share with us!

Latest News: The possibility of life on other worlds has fueled humankind's imagination for centuries. Over the past 20 years, the explosion of discoveries of planets orbiting other stars has sparked the search for worlds like Earth that could sustain life. Most of those candidates were found with other telescopes, including NASA's Kepler space observatory. NASA's Hubble Space Telescope has also made some unique contributions to the planet hunt. Astronomers used Hubble, for example, to make the first measurements of the atmospheric composition of extrasolar planets.

Now, astronomers have used Hubble to conduct the first search for atmospheres around temperate, Earth-sized planets beyond our solar system, uncovering clues that increase the chances of habitability on two exoplanets. They discovered that the exoplanets TRAPPIST-1b and TRAPPIST-1c, approximately 40 light-years away, are unlikely to have puffy, hydrogen-dominated atmospheres usually found on gaseous worlds. Those dense atmospheres act like a greenhouse, smothering any potential life. Observations from NASA's upcoming James Webb Space Telescope will help determine the full composition of these atmospheres and hunt for potential biosignatures, such as carbon dioxide and ozone, and methane.

In the Baltimore area? Join us this weekend at Artscape! Visit the Space Telescope Science Institute at the Pinkard Gallery for a display of museum-style images of Hubble’s greatest hits, our ViewSpace video exhibit on astronomical discoveries, an interactive touchscreen featuring visualizations of cosmic events, volunteers in clean room “bunny suits” discussing the science and engineering of space telescopes, and more. We’ll be sharing info on Hubble as well as the upcoming James Webb Space Telescope and Wide Field Infrared Survey Telescope (WFIRST). Be sure to bring young astronomy fans to Kidscape Academy at the Corpus Christi Church lot on July 15 and 16, where we’ll be doing light and color activities and demonstrating an infrared camera. Light and color activities are from noon-8 p.m. July 15 only. Infrared camera demonstrations are at noon, 2, 4 and 6 p.m. July 15, and noon and 3 p.m. July 16.

Introduction

HubbleSite.org is the online home of NASA's Hubble Space Telescope. HubbleSite is produced by the Space Telescope Science Institute in Baltimore, MD, which conducts Hubble's science mission.

Nearly 400 years after Galileo first observed the heavens through a telescope, we continue to seek answers to age-old questions about the universe. And while the technology has evolved over the centuries, the inquiry remains essentially the same: What's out there, where did it come from, and what does it mean?

At the Space Telescope Science Institute (STScI), we're working hard to study and explain the once-unimaginable celestial phenomena now made visible by the Hubble Space Telescope's cutting-edge technology.

HubbleSite is produced by the Space Telescope Science Institute's Office of Public Outreach.
