Hubble Space Telescope

Shared publicly  - 
 
A new analysis of 13 supernovae — including archived data from NASA's Hubble Space Telescope — is helping astronomers explain how some young stars exploded sooner than expected, hurling them to a lonely place far from their host galaxies.

Astronomers hypothesize that a pair of supermassive black holes in the merging galaxies can provide the gravitational slingshot to rocket the binary stars into intergalactic space. Hubble observations reveal that nearly every galaxy has a massive black hole at its center.

According to astronomer Ryan Foley's scenario, after two galaxies merge, their black holes migrate to the center of the new galaxy, each with a trailing a cluster of stars.

As the black holes dance around each other, slowly getting closer, one of the binary stars in the black holes' entourage may wander too close to the other black hole. Many of these stars will be flung far away, and those ejected stars in surviving binary systems will orbit even closer after the encounter, which speeds up the merger.

Please join +Tony Darnell Dr.+Carol Christian and +Scott Lewis as they discuss these observations with lead investigator Dr. Ryan Foley of the University of Illinois.  As always, we welcome your questions and comments.

+Krystal Gardner So sorry to tell that Jupiter will be nowhere near the moon tomorrow night and there will never ever be a "double moon". It's a hoax ! Check out http://earthsky.org/astronomy-essentials/double-moon-on-august-27
Bottom line: Saturn is the dominant planet in August, 2015. Four of the five visible planets – Mercury, Venus, Mars and Jupiter, are just about visible, but hide in the glare of evening or morning twilight, close to the horizon.
Nevertheless, the moon will be one day away from being a big beautiful full "Supermoon".
It sickens me that idiots get a cheap thrill out of misleading people like you and your son. If they knew what effect their ill-thought out stunts had, maybe they wouldn't continue with this nonsense.
Please, please, let him down gently and show him the moon, Saturn will be up in the southwest, and the stars are always beautiful.
Alternatively, perhaps you could look at https://www.heavens-above.com/? and find out whether the International Space Station or some other visible satellites will be passing over your house tomorrow night.

Latest News: What happens when you find something in the wrong place at the wrong time? That's a question astronomers have been trying to answer after finding several exploding stars outside the cozy confines of galaxies, where most stars reside. These wayward supernovae also have puzzled astronomers because they exploded billions of years before their predicted detonations. Astronomers using archived observations from several telescopes, including the Hubble Space Telescope, have developed a theory for where these doomed stars come from and how they arrived at their current homes.

Researchers using +NASA  +Hubble Space Telescope  have detected a stratosphere and temperature inversion in the atmosphere of a planet several times the mass of Jupiter, called WASP-33b.

Earth's stratosphere sits above the troposphere, the turbulent, active-weather region that reaches from the ground to the altitude where nearly all clouds top out. In the troposphere, the temperature is warmer at the bottom — ground level — and cools down at higher altitudes. The stratosphere is just the opposite: There, the temperature rises at higher altitudes. This is called a temperature inversion, and it happens because ozone in the stratosphere absorbs some of the sun's radiation, preventing it from reaching the surface and warming this layer of the atmosphere. Similar temperature inversions occur in the stratospheres of other planets in our solar system, such as Jupiter and Saturn.

But WASP-33b is so close to its star that its atmosphere is a scathing 10,000 degrees Fahrenheit, and its atmosphere is so hot the planet might actually have titanium oxide rain.

Please join +Tony Darnell Dr, +Carol Christian and +Scott Lewis as they discuss the atmosphere of this Jupiter-sized #exoplanet with the astronomers who made the observations.

The first indications of life outside our solar system won't be pictures of blue oceans or aliens signalling hello -- they'll be chemical traces in the atmosphere of a far-away planet. Find out how Hubble is helping astronomers study the atmospheres of extrasolar planets in our new 25th anniversary science article: "Are There Habitable Planets Outside Our Solar System?" 
In the last two decades, NASA has been at the forefront of discovering planets beyond our solar system. Hubble explores the nature of these worlds, from orbits to atmospheres, and helps answer fundamental questions about how extrasolar planetary systems compare to ours.

Latest News: Astronomers have uncovered a unique process for how the universe's largest elliptical galaxies continue making stars long after their peak years of star birth. Hubble's exquisite high resolution and ultraviolet-light sensitivity allowed the astronomers to see brilliant knots of hot, blue stars forming along the jets of active black holes found in the centers of giant elliptical galaxies.

Astronomers using and Telescopes use Microlensing to Find Uranus-Sized Exoplanet


The majority of planets discovered outside our solar system orbit close to their parent stars because these planets are the easiest to find. But to fully understand how distant planetary systems are put together, astronomers must conduct a census of all the planets around a star. So they need to look farther away from the star-from about the distance of Jupiter is from our sun, and beyond.

Now, astronomers using NASA's Hubble Space Telescope and the W. M. Keck Observatory in Hawaii have confirmed the existence of a Uranus-sized exoplanet orbiting far from its central star, discovered through a technique called gravitational microlensing. Microlensing occurs when a foreground star magnifies the light of a background star that momentarily aligns with it. The unique signature of the event, which is influenced by the relative motion of the stars across space, can reveal clues to the nature of the foreground star and any associated planets. Gravitational microlensing can find cold planets in long-period orbits that other methods cannot detect.

This finding opens a new piece of discovery space in the extrasolar planet hunt: to uncover planets as far from their central stars as Jupiter and Saturn are from our sun.

Have you ever wondered how astronomers simulate the large-scale structure of the universe?  How do they answer questions like, 'What will #JWST show us?' or 'What can we expect to learn from #WFIRST ?'

The Space Telescope Science Institute is hosting a mini-workshop this week featuring techniques for simulating the universe where they delve into these questions and many more.

This workshop will focus on the interface of models and survey design: how can we best inject and extract astrophysical insight into and from data simulations?

One of the main aims is to identify common ground between various ongoing data simulation efforts associated with diverse facilities on the ground and in space (e.g., ELTs, JWST, LSST, PanSTARRS, WFIRST, ALMA, Euclid etc.).

Please join +Tony Darnell Dr +Carol Christian and +Scott Lewis as they discuss simulating the universe with astronomers +Molly Peeples and Joshua Peek.  We look forward to hearing your comments and questions as well!

This image shows our previous best view of Pluto, provided by the Hubble Space Telescope, as it morphs into the spectacular new image from the New Horizons mission. The Hubble image was released in 2010, and the New Horizons image of the same region was taken on July 13 as the spacecraft -- nearing the culmination of its decade-long journey -- successfully captured the first detailed images of the distant dwarf planet. #Plutoflyby

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.
