Далеко не у каждого сбывается мечта стать космическим героем, но полюбоваться вселенной, убежать от обыденной реальности и помечтать мы всегда можем с помощью замечательных научно-фантастических фильмов и книг.
Каждый день я выделяю время, чтобы насладиться новыми фотографиями на страницах астронавтов и NASA. Самыми красивыми и интересными фото за последний месяц хочу поделиться с вами в этот осенний хмурый день.
This new image of the spiral galaxy NGC 3521 from the NASA/ESA Hubble Space Telescope is not out of focus. Instead, the galaxy itself has a soft, woolly appearance as it a member of a class of galaxies known as flocculent spirals. Like other flocculent galaxies, NGC 3521 lacks the clearly defined, arcing structure to its spiral arms. In flocculent spirals, fluffy patches of stars and dust show up here and there throughout their disks. Sometimes the tufts of stars are arranged in a generally spiraling form, as with NGC 3521, but illuminated star-filled regions can also appear as short or discontinuous spiral arms. NGC 3521 is located almost 40 million light-years away in the constellation of Leo (The Lion). Image credit: ESA/Hubble & NASA and S.

Water on Mars! New findings from our Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Dark, narrow streaks on Martian slopes such as these at Hale Crater are inferred to be formed by seasonal flow of water on contemporary Mars. The streaks are roughly the length of a football field. The imaging and topographical information in this processed, false-color view. These dark features on the slopes are called "recurring slope lineae" or RSL. Planetary scientists detected hydrated salts on these slopes at Hale Crater, corroborating the hypothesis that the streaks are formed by briny liquid water.

Solar Loops: An active region viewed in profile put on quite a show of erupting plasma and looping arches on Sept. 22-23. The loops, seen above the sun's surface on the right, are light emissions from charged particles spinning along magnetic field lines that dance through the sun's atmosphere. The region, which appeared as a sunspot group in visible light, was observed here in two wavelengths of extreme ultraviolet light over a period of about 40 hours. Though invisible to our eyes, light emissions in the extreme ultraviolet wavelength of 171 Angstroms are typically colorized in gold, while emissions in 304 angstroms are colorized in red.

The International Space Station crew witness nightly scenes of our Earth's beauty after performing their duties. Framed by the edge of a station solar panel, the city of Moscow, Russia sparkles in the night with spoke streets streaming out across the land while an aurora of blue, white and purple contrast the star-filled sky. Today on the station, NASA astronaut Kjell Lindgren (@astro_kjell) is completing cable connections and routing today in the Unity module while NASA astronaut Scott Kelly (@StationCDRKelly) replaced electronic gear inside a science freezer before attaching instruments and sensors to himself for the Sprint exercise study. #Moscow #Russia #aurora #beauty #citylights #photography #space #spacestation #NASA #YearInSpace #science #research
On the night of Oct. 8, a photographer in Harstad, Norway captured this image of the dancing northern lights. Auroras are created when fast-moving, magnetic solar material strikes Earth's magnetic bubble, the magnetosphere. This collision rattles the magnetosphere in an event called a geomagnetic storm, sending trapped charged particles zooming down magnetic field lines towards the atmosphere, where they collide brilliantly with molecules in the air, creating auroras. Though many geomagnetic storms are associated with clouds of solar material that explode from the sun in an event called a coronal mass ejection, or CME, this storm was caused by an especially fast stream of solar wind. "Geomagnetic storms caused by high-speed solar wind streams aren't uncommon," said Leila Mays, a space physicist at our Goddard Space Flight Center in Greenbelt, Maryland. "Near solar minimum-when solar activity like CMEs are less frequent-these fast streams are actually the most common cause of geomagnetic storms that create auroras."

Scientists compared ground-based videos of pulsating auroras—a certain type of aurora that appears as patches of brightness regularly flickering on and off—with satellite measurements of the numbers and energies of electrons raining down towards the surface from inside Earth’s magnetic bubble, the magnetosphere. The team found something unexpected: A drop in the number of low-energy electrons, long thought to have little or no effect, corresponds with especially fast changes in the shape and structure of pulsating auroras. This image of a colorful aurora was taken in Delta Junction, Alaska, on April 10, 2015. All auroras are created by energetic electrons, which rain down from Earth’s magnetic bubble and interact with particles in the upper atmosphere to create glowing lights that stretch across the sky.

NASA astronaut Scott Kelly (@StationCDRKelly) captured this photograph of the green lights of the aurora from the International Space Station on Oct. 7. Sharing with his social media followers, Kelly wrote, "The daily morning dose of #aurora to help wake you up. #GoodMorning from @ISS! #YearInSpace Image credit: NASA #nasa #space #iss #spacestation #earth
Pluto's haze layer shows its blue color in this picture taken by our New Horizons Ralph/Multispectral Visible Imaging Camera (MVIC). The high-altitude haze is thought to be similar in nature to that seen at Saturn's moon Titan. The source of both hazes likely involves sunlight-initiated chemical reactions of nitrogen and methane, leading to relatively small, soot-like particles (called tholins) that grow as they settle toward the surface. This image was generated by software that combines information from blue, red and near-infrared images to replicate the color a human eye would perceive as closely as possible.

When stars that are around the mass of the sun reach their final stages of life, they shed their outer layers into space, which appear as glowing clouds of gas called planetary nebulae. The ejection of mass in stellar burnout is irregular and not symmetrical, so that planetary nebulae can have very complex shapes. In the case of this one, the nebula forms a winding blue cloud that perfectly aligns with two stars at its center. In 1999 astronomers discovered that the star at the upper right is in fact the central star of the nebula, and the star to the lower left is probably a true physical companion of the central star. For tens of thousands of years the stellar core will be cocooned in spectacular clouds of gas and then, over a period of a few thousand years, the gas will fade away into the depths of the universe. The curving structure of this planetary nebula resembles a last goodbye before the star reaches its final stage of retirement as a white dwarf.

The dark area across the top of the sun in this image is a coronal hole, a region on the sun where the magnetic field is open to interplanetary space, sending coronal material speeding out in what is called a high-speed solar wind stream. The high-speed solar wind originating from this coronal hole, imaged here on Oct. 10 by our Solar Dynamics Observatory, created a geomagnetic storm near Earth that resulted in several nights of auroras. This image was taken in wavelengths of 193 Angstroms, which is invisible to our eyes and is typically colorized in bronze. Image credit: NASA/SDO #nasa #space #sdo #sun #earth #nasabeyond #science
New Spaceflight Record! Just before the 15th anniversary of continuous human presence on the International Space Station (@ISS) on Nov. 2, 2015, U.S. astronaut Scott Kelly (@StationCDRKelly) is breaking spaceflight records. On Friday, Oct. 16, Kelly begins his 383rd day living in space, surpassing U.S. astronaut Mike Fincke's record of 382 cumulative days. Kelly will break another record Oct. 29 on his 216th consecutive day in space, when he will surpass astronaut Michael Lopez-Alegria's record for the single-longest spaceflight by an American. Lopez-Alegria spent 215 days in space as commander of the Expedition 14 crew in 2006. In this July 12 photograph, Kelly is seen inside the Cupola, a special module which provides a 360-degree viewing of the Earth and the space station. On each additional day he spends in orbit as part of his one-year mission, Kelly will add to his record and to our understanding of the effects of long-duration spaceflight. Kelly is scheduled to return to Earth on March 3, 2016, by which time he will have compiled 522 total days living in space during four missions.

Hubble Sees Elegant Spiral Hiding a Hungry Monster NGC 4639 is a beautiful example of a type of galaxy known as a barred spiral. It lies over 70 million light-years away in the constellation of Virgo and is one of about 1,500 galaxies that make up the Virgo Cluster. In this image, taken by the Hubble Space Telescope, one can clearly see the bar running through the bright, round core of the galaxy. Bars are found in around two-thirds of spiral galaxies, and are thought to be a natural phase in their evolution. The galaxy’s spiral arms are sprinkled with bright regions of active star formation. Each of these tiny jewels is actually several hundred light-years across and contains hundreds or thousands of newly formed stars. But NGC 4639 also conceals a dark secret in its core — a massive black hole that is consuming the surrounding gas. Image credit: ESA/Hubble & NASA
A mass of plasma gathered itself into a twisting mass, spun around for a bit, then rose up and broke apart over a 10-hour period (Oct. 13, 2015). The image and video were produced with a combination of two wavelengths of extreme ultraviolet light. Prominences are unstable clouds of gas tethered above the surface of the Sun by magnetic forces. Much of the jittering and odd jumping motions above the surface were artifacts caused by brightening and contrast changes used to bring out the detail and structure of the prominence.

This galaxy cluster is home to one of the most powerful eruptions ever observed! X-rays detected by our Chandra X-Ray Observatory (blue) show the hot gas that comprises much of the mass of this enormous object. Within the Chandra data, holes, or cavities, can be seen. These cavities were created by an outburst from a supermassive black hole at the center of the cluster, which ejected the enormous jets detected in radio waves (pink) detected by the Very Large Array. These data have been combined with optical data from the Hubble Space Telescope of galaxies in the cluster and stars in the field of view (orange).

Big Bang Frontiers: Observations have taken advantage of gravitational lensing to reveal the largest sample of the faintest and earliest known galaxies in the universe. Some of these galaxies formed just 600 million years after the big bang and are fainter than any other galaxy yet uncovered by the Hubble Space Telescope. The team has determined for the first time with some confidence that these small galaxies were vital to creating the universe that we see today.

Artist's conception of a hot Jupiter, previously thought to be lonely planets. Scientists have now discovered one hot Jupiter with two close companions, leading to new ideas about planet formation. Until now, some 300 hot Jupiters have been identified over the past two decades, and this is the first time any close-in planets were discovered. This new discovery is helpful to scientists who are trying to understand how planets form and move in solar systems.

This image shows the galaxy Messier 94, which lies in the small northern constellation of the Hunting Dogs, about 16 million light-years away. Within the bright ring or starburst ring around Messier 94, new stars are forming at a high rate and many young, bright stars are present within it. The cause of this peculiarly shaped star-forming region is likely a pressure wave going outwards from the galactic center, compressing the gas and dust in the outer region. The compression of material means the gas starts to collapse into denser clouds. Inside these dense clouds, gravity pulls the gas and dust together until temperature and pressure are high enough for stars to be born.
