Hubble's spies a cool galaxy with a hot corona, 150 million light-years from Earth

Galaxy NGC 6753, imaged here by the NASA/ESA Hubble Space Telescope, is a whirl of color — the bursts of blue throughout the spiral arms are regions filled with young stars glowing brightly in ultraviolet light, while redder areas are filled with older stars emitting in the cooler near-infrared.

But there is more in this galaxy than meets the Hubble eye. At 150 million light-years from Earth, astronomers highlighted NGC 6753 as one of only two known spiral galaxies that were both massive enough and close enough to permit detailed observations of their coronas. Galactic coronas are huge, invisible regions of hot gas that surround a galaxy’s visible bulk, forming a spheroidal shape. Coronas are so hot that they can be detected by their X-ray emission, far beyond the optical radius of the galaxy. Because they are so wispy, these coronas are extremely difficult to detect.

Galactic coronas are an example of telltale signs astronomers seek to help them determine how galaxies form. Despite the advances made in past decades, the process of galaxy formation remains an open question in astronomy. Various theories have been suggested, but since galaxies come in all shapes and sizes — including elliptical, spiral, and irregular — no single theory has so far been able to satisfactorily explain the origins of all the galaxies we see throughout the Universe.

NASA Tracking Hurricane Maria on Bahamas Approach

NASA-NOAA's Suomi NPP satellite provided a look at Maria's temperatures to find the strongest sides of the storm, while NOAA's GOES satellite revealed the extent of the storm in a visible image as it moved toward the Bahamas.

On Sept. 22 at 3:18 a.m. EDT (0718 UTC) the VIIRS instrument aboard NASA-NOAA's Suomi NPP satellite provided a thermal image of Hurricane Maria north of Hispaniola and nearing the Bahamas. The image showed highest coldest clouds around the eyewall and in bands of thunderstorms to the northeast and south and southeast of the center, stretching over Hispaniola and Puerto Rico. Those clouder clouds have the capability of producing heavy rainfall.

In the summer of 2018, NASA is launching Parker Solar Probe, a spacecraft that will get closer to the Sun than any other in human history. The Probe will fly directly through the Sun’s atmosphere, called the corona. Getting better measurements of this region is key to understanding our Sun. For instance, the Sun releases a constant outflow of solar material, called the solar wind. We think the corona is where this solar wind is accelerated out into the solar system, and Parker Solar Probe’s measurements should help us pinpoint how that happens.

A Cut in the Clouds

Like a ship carving its way through the sea, the South Georgia and South Sandwich Islands parted the clouds. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image on February 2, 2017. The ripples in the clouds are known as gravity waves.

Critical extra time that could help protect astronauts from space weather identified by NASA scientist

Our constantly-changing sun sometimes erupts with bursts of light, solar material, or ultra-fast energized particles — collectively, these events contribute to space weather. In a study published Jan. 30, 2017, in Space Weather, scientists from NASA and the National Center for Atmospheric Research, or NCAR, in Boulder, Colorado, have shown that the warning signs of one type of space weather event can be detected tens of minutes earlier than with current forecasting techniques – critical extra time that could help protect astronauts in space.

Earth’s magnetic field and atmosphere protect us on the ground from most of the harmful effects of space weather, but astronauts in low-Earth orbit — or even, one day, in interplanetary space — are more exposed to space weather, including bursts of fast-moving particles called solar energetic particles, or SEPs.

This composite image shows a coronal mass ejection, a type of space weather linked to solar energetic particles, as seen from two space-based solar observatories and one ground-based instrument. The image in gold is from NASA’s Solar Dynamics Observatory, the image in blue is from the Manua Loa Solar Observatory’s K-Cor coronagraph, and the image in red is from ESA and NASA’s Solar and Heliospheric Observatory.

NASA's Webb Telescope Clean Room 'Transporter'

What looks like a teleporter from science fiction being draped over NASA's James Webb Space Telescope, is actually a "clean tent." The clean tent protects Webb from dust and dirt when engineers at NASA's Goddard Space Flight Center in Greenbelt, Maryland transport the next generation space telescope out of the relatively dust-free cleanroom and into the shirtsleeve environment of the vibration and acoustics testing areas. In two years, a rocket will be the transporter that carries the Webb into space so it can orbit one million miles from Earth and peer back over 13.5 billion years to see the first stars and galaxies forming out of the darkness of the early universe.

What happens when the lights are turned out in the enormous clean room that currently houses NASA's James Webb Space Telescope?
The technicians who are inspecting the telescope and its expansive golden mirrors look like ghostly wraiths in this image as they conduct a "lights out inspection" in the Spacecraft Systems Development and Integration Facility (SSDIF) at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

The clean room lights were turned off to inspect the telescope after it experienced vibration and acoustic testing. The contamination control engineer used a bright flashlight and special ultraviolet flashlights to inspect for contamination because it's easier to find in the dark.

NASA photographer Chris Gunn said "The people have a ghostly appearance because it's a long exposure." He left the camera's shutter open for a longer than normal time so the movement of the technicians appear as a blur. He also used a special light "painting" technique to light up the primary mirror.

The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built. Webb is an international project led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

The sun emitted a trio of mid-level solar flares on April 2-3, 2017. The first peaked at 4:02 a.m. EDT on April 2, the second peaked at 4:33 p.m. EDT on April 2, and the third peaked at 10:29 a.m. EDT on April 3. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured images of the three events. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however — when intense enough — they can disturb the atmosphere in the layer where GPS and communications signals travel.

Caption: NASA's Solar Dynamics Observatory captured this image of a solar flare peaking at 10:29 a.m. EDT on April 3, 2017, as seen in the bright flash near the sun’s upper right edge. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is typically colorized in teal.

James Webb Uzay Teleskopu

The James Webb Uzay Teleskobu (JWUT) eskiyen Hubble Uzay Teleskobu'nun kısmen ardılı olacak şekilde planlanan bir kızılötesi uzay teleskopudur.

JWUT tam anlamıyla bir ardıl olarak görev yapmayacak çünkü Hubble'ın gözlemleyebildiği bütün ışık dalga boylarına duyarlı olmayacak. Esas bilimsel hedefi evrende yer alan daha uzaktaki cisimleri; diğer temel cihazlar veya Hubble'ın görmediği cisimleri gözlemlemek olacak.

JWUT, NASA'nın başkanlığında 15 farklı devletin, Avrupa Uzay Ajansı ve Kanada Uzay Ajansı'nın ortak yürüttüğü bir proje olan James Webb Teleskopu'nun 2018 yılının Ekim ayında hizmete girmesi bekleniyor. 2018 yılında fırlatılması planlanan ve yeni bir çığır açacak olan James Webb Uzay Teleskobu (JWST), gezegen avcıları da dahil olmak üzere muhtemelen her türden gökbilimci için bir nimet olacaktır. Kırmızı ötesi ışığı gözlemlemek için ayarlanmış olan 6,5 metrelik bu teleskop, Dünya'dan neredeyse 1.600.000 kilometre uzaklıkta yörüngeye yerleştirilecektir. Bu uzaklık, Dünya ile Ay arasındaki uzaklığın dört katı kadardır. JWST üzerinde yer alacak olan hassas aygıtlar, dev gezegenlerin ve gezegen sistemlerinin kırmızı ötesi görüntülerini çekme ve tayflarını ölçerek yaşlarını ve kütlelerini belirleme imkanına sahip olacaktır. Bunların dışında JWST, başka yıldızların çevresinde yer alan disklerin tayf ölçümlerini yaparak, gezegen sistemlerinin doğmasına olanak sağlayan türden olan disklerin bileşenlerini tanımlamaya da imkan verecektir. Son derece hassas aygıtları ve büyük aynasıyla JWST, gezegenlerin doğduğu toz disklerini gözlemleyebilmenin yanında, kendi yıldızlarının önünden geçen gezegenlerin havaküre bileşenlerini de gözlemleyebilecektir. Her ne kadar JWST özellikle gezegen bulmak için geliştirilmiş bir teleskop olmasa da, gelişkin yetenekleri bu teleskobun gelecekte yeni gezegenleri inceleyen ve güneş sistemimizin nasıl oluştuğu ve nasıl evrim geçirdiği konularını araştıran gökbilimciler için önemli bir araç haline gelmesi konusunda ümit vermektedir.

The Eagle and The Swan: The Eagle Nebula and the Swan Nebula span this broad starscape, a telescopic view toward the Sagittarius spiral arm and the center of our Milky Way galaxy. The Eagle, also known as M16, is at top and M17, the Swan, at bottom of the frame showing the cosmic clouds as brighter regions of active star-formation. They lie along the spiral arm suffused with reddish emission charactistic of atomic hydrogen gas, and dusty dark nebulae. M17, also called the Omega Nebula, is about 5500 light-years away, while M16 is some 6500 light-years distant. The center of both nebulae are locations of well-known close-up images ofstar formation from the Hubble Space Telescope. In this mosaic image that extends about 3 degrees across the sky, narrowband, high-resultion image data has been used to enhance the central regions of the Eagle and Swan. The extended wings of the Eagle Nebula spread almost 120 light-years. The Swan is over 30 light-years across.

Operation IceBridge is flying over Greenland to measure how much of the ice sheet has melted over the course of the summer.

This image was taken from an altitude of 28,000 feet during a research flight on Aug. 29. It shows the calving front — the end of the glacier, from where it sheds chunks of ice — of the Zachariae Isstrom glacier in northeast Greenland. The flights, which began on Aug. 25 and will go on until Sept. 21, repeat paths flown this spring and aim to monitor seasonal changes in the elevation of the ice sheet.

Operation IceBridge is NASA's longest-running airborne survey to monitor polar ice. Its mission is to collect data that helps us understand how polar land and sea ice are changing. Operation IceBridge maintains continuity of measurements between ICESat missions, which survey polar ice from space. The planned overlap with ICESat-2 will help scientists validate the satellite's measurements.

Truth is just truth -- Perception is Reality -- truth is simple,it doesn't require years of learning, fantastic feats or fancy words, truth is just truth. Lies on the other hand change constantly and are rarely understood, often taking volumes of books,groups of scientists and collections of scholars to maintain.

This doesn't apply to real scientists like @such.chris
And the rest of his crew.
