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


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

Recent space telescope missions such as Kepler and Spitzer have given us unprecedented data that have shown that there are many, many planets orbiting other stars.  Current estimates show that there are enough planets in our galaxy that for every star in the Milky Way, there are on average 1.6 planets in orbit around them.  Many of these planets are like the Earth and have the potential to harbor life.

In our first FutureInSpace Hangout, we will explore this relatively brand new study in space astronomy with expert members of the American Astronomical Society, Dr. Natalie Batalha and Dr Sara Seager.  We will discuss the current state of exoplanet research and look at what exciting results may be in store for us as we deploy the next generation of space telescope like the James Webb Space Telescope (JWST), the Wide-Field Infrared Space Telescope (WFIRST), the Transiting Exoplanet Survey Satellite (TESS) and the future High Definition Space Telescope (HDST).

Please join +Tony Darnell Dr. +Alberto Conti and Dr. Harley Thronson and bring your questions and comments for our experts and we look forward to "Hanging Out" with you.

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.

A huge congratulations to the New Horizons team on the spacecraft's historic first visit to Pluto, happening now! 
Pluto nearly fills the frame in this image from the Long Range Reconnaissance Imager (LORRI) aboard NASA's New Horizons spacecraft, taken on July 13, 2015 when the spacecraft was 476000 miles (768000 kilometers) from the surface. This is the last and most detailed image sent to Earth before the ...

The Andromeda galaxy is our Milky Way's nearest neighbor in space. The majestic spiral of over 100 billion stars is comparable in size to our home galaxy. At a distance of 2.5 million light-years, it is so close to us the galaxy can be seen as a cigar-shaped smudge of light high in the autumn sky.

But if you could see the huge bubble of hot, diffuse plasma surrounding it, it would appear 100 times the angular diameter of the full Moon!

The gargantuan halo is estimated to contain half the mass of the stars in the Andromeda galaxy itself. It can be thought of as the "atmosphere" of a galaxy. Astronomers using Hubble identified the gas in Andromeda's halo by measuring how it filtered the light of distant bright background objects called quasars. It is akin to seeing the glow of a flashlight shining through a fog.

This finding promises to tell astronomers more about the evolution and structure of one of the most common types of galaxies in the universe.

Please join +Tony Darnell Dr.+Carol Christian and +Scott Lewis as they discuss this latest finding from #Hubble with the astronomers who made the observations.

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.
