From approximately 22,236 miles in space, NASA and the National Oceanic and Atmospheric Administration's (NOAA) newest Geostationary Operational Environmental Satellite – GOES-15 – took its first full-disk infrared image of the Earth on April 26, 2010.Infrared (IR) imagery enables weather forecasters to gather information such as Earth, cloud and sea surface temperatures; derive winds and temperature and moisture profiles of the atmosphere; and detect fires and track the movement of the smoke plumes from them.
Infrared radiation is electromagnetic radiation. Its wavelength is longer (and the frequency lower) than that of visible light, but the wavelength is shorter (and the frequency higher) than that of microwaves.
"This (image) marks the final stage of the critical events for the spacecraft and indicates that the visible and infrared spacecraft imaging instruments are performing as expected," said Andre' Dress, the NASA GOES Deputy Project Manager at NASA's Goddard Space Flight Center in Greenbelt, Md. "We're looking forward to more imagery as we finish up post-launch testing."
The first GOES-15 full-disk infrared image was from the Imager. The GOES Imager is a multi-channel instrument designed to sense radiant and solar-reflected energy from the Earth.The first full-disk infrared image of the Earth was taken on April 26 at 17:30 UTC (1:30 p.m. EDT). It showed clouds associated with low pressure areas over the Ohio Valley and southern Minnesota, and the cold front coming into the Pacific Northwest. The image also shows strong thunderstorms and associated clouds in South Florida, convection along the Inter-Tropical Convergence Zone near the equator, the clouds associate with the sub-tropical jet stream from the Pacific Ocean through south Texas and snow on the ground in the Rocky Mountains.
The Sounder is another instrument on GOES-15 which also took Infrared images of the Earth. The Sounder is designed to provide data from which atmospheric temperature and moisture profiles, surface and cloud-top temperatures, and ozone distribution can be deduced by mathematical analysis.
GOES-15 also provides visible images of Earth. On April 6, GOES-15 captured its first visible image of Earth.
NASA testing of the spacecraft and its instruments will continue through the entire post launch test period expected to end in late August 2010. This will be followed by the NOAA Science Test. The GOES series of U.S. satellites are developed by a joint NASA-NOAA-Industry partnership, launched by NASA (with industry partners), and operated by NOAA.
In general, the GOES-15 infrared data has a much cleaner signal to noise ratio than the previous GOES-8 through -12 series. In addition, GOES-15 has much improved image navigation and registration. The GOES Imager is used for a host of applications, ranging from meteorological, climate, oceanographic and hazards. The Sounder is used to estimate temperature and moisture profiles in the atmosphere. It can also derive information on clouds and certain trace gases such as upper-level ozone.The GOES-15 Imager was built by ITT Industries in Fort Wayne, Ind. The first public Imager infrared image showed the earth-ocean-atmosphere system in five spectral regions. These are: a visible band, a shortwave window band, a water vapor band, a longwave window band and a carbon dioxide sensitive band.
The GOES-15 Sounder was also built by ITT and an infrared sector scan of the United States showed the earth-ocean-atmosphere in 18 infrared spectral regions. These allow one to 'profile' atmospheric temperature and moisture. The IR bands on the sounder range from the longwave (14.7 micrometers) to the shortwave (3.7 micrometers).
GOES-15, launched on March 4, 2010, from Cape Canaveral, Fla., joins three other NOAA operational GOES spacecraft that help the agency's forecasters track life-threatening weather and solar activity that can impact the satellite-based electronics and communications industry. After four more months of tests, GOES-15 will be placed in orbital storage mode, ready for activation if any of NOAA's operational GOES spacecraft experiences trouble.GOES-15 is the third and final spacecraft to be launched in the GOES N-P Series of geostationary environmental weather satellites. With two operational satellites, they provide weather observations that cover over 50 percent of the Earth's surface.
NASA's GOES Project is located at NASA's Goddard Space Flight Center, Greenbelt, Md. On March 24 the NASA and NOAA team began post launch verification testing, which will last for approximately 150 days. Once all the systems are checked out, the satellite will be turned over to NOAA for operational control and will be stored in-orbit, ready for activation should one of the operational GOES satellites degrade or exhaust their fuel.

Double Black Holes


This image from the Chandra X-ray Observatory shows the central region of the starburst galaxy M82 and contains two bright X-ray sources of special interest. New studies with Chandra and ESA's XMM-Newton show that these two sources may be intermediate-mass black holes, with masses in between those of the stellar-mass and supermassive variety. These "survivor" black holes avoided falling into the center of the galaxy and could be examples of the seeds required for the growth of supermassive black holes in galaxies, including the one in the Milky Way.
This is the first case where good evidence for more than one mid-sized black hole exists in a single galaxy. The evidence comes from how their X-ray emission varies over time and analysis of their X-ray brightness and spectra, i.e., the distribution of X-rays with energy. These results are interesting because they may help address the mystery of how supermassive black holes in the centers of galaxies form. M82 is located about 12 million light years from Earth and is the nearest place to us where the conditions are similar to those in the early Universe, with lots of stars forming.
Multiple observations of M82 have been made with Chandra beginning soon after launch. The Chandra data shown here were not used in the new research because the X-ray sources are so bright that some distortion is introduced into the X-ray spectra. To combat this, the pointing of Chandra is changed so that images of the sources are deliberately blurred, producing fewer counts in each pixel.

Starburst Galaxy M82


This composite image of the nearby starburst galaxy M82 shows Chandra X-ray Observatory data in blue, optical data from the Hubble Space Telescope in green and orange, and infrared data from the Spitzer Space Telescope in red. The pullout is a Chandra image that shows the central region of the galaxy and contains two bright X-ray sources -- identified in a labeled version -- of special interest.
New studies with Chandra and ESA's XMM-Newton show that these two sources may be intermediate-mass black holes, with masses in between those of the stellar-mass and supermassive variety. These "survivor" black holes avoided falling into the center of the galaxy and could be examples of the seeds required for the growth of supermassive black holes in galaxies, including the one in the Milky Way.
This is the first case where good evidence for more than one mid-sized black hole exists in a single galaxy. The evidence comes from how their X-ray emission varies over time and analysis of their X-ray brightness and spectra, i.e., the distribution of X-rays with energy.
One of the black holes is located at a projected distance of 290 light years from the center of M82 (labeled with an "x") and its mass is estimated to be between 12,000 and 43,000 times the mass of the Sun. At this close distance, if the black hole was born at the same time as the galaxy and its mass was more than about 30,000 solar masses, it likely would have been pulled into the center of the galaxy. That is, it may have just escaped falling into the supermassive black hole that is presumably located in the center of M82. The second black hole is located 600 light years in projection away from the center of M82. The best model for this M82 black hole has a mass between 200 and 800 times that of the Sun, and tilted at an angle between 60 and 80 degrees, meaning that the disk is viewed almost side-on. However, because of relativistic effects for a rapidly spinning black hole with this mass, a disk viewed at a high inclination is almost as bright as one viewed at a low inclination (i.e., face-on).
These results are interesting because they may help address the mystery of how supermassive black holes in the centers of galaxies form. M82 is located about 12 million light years from Earth and is the nearest place to us where the conditions are similar to those in the early Universe, with lots of stars forming.

Asteroides



Building Planets


This artist's animation illustrates a massive asteroid belt in orbit around a star the same age and size as our Sun. Asteroids are chunks of rock from "failed" planets, which never managed to coalesce into full-sized planets. Asteroid belts can be thought of as construction sites that accompany the building of rocky planets.Announced on April 28, 2010, scientists using NASA’s Infrared Telescope Facility have detected water-ice and carbon-based organic compounds on the surface of an asteroid. The cold hard facts of the discovery of the frosty mixture on one of the asteroid belt's largest occupants, suggests that some asteroids, along with their celestial brethren, comets, were the water carriers for a primordial Earth.Image credit: NASA/JPL-Caltech

Oil Slick Spreads off Gulf Coast


Oil Slick Spreads off Gulf Coast

NASA's Aqua satellite captured this image of the Gulf of Mexico on April 25, 2010 using its Moderate Resolution Imaging Spectroradiometer (MODIS) instrument. With the Mississippi Delta on the left, the silvery swirling oil slick from the April 20 explosion and subsequent sinking of the Deepwater Horizon drilling platform is highly visible. The rig was located roughly 50 miles southeast of the coast of Louisiana.
The oil slick may be particularly obvious because it is occurring in the sunglint area, where the mirror-like reflection of the Sun off the water gives the Gulf of Mexico a washed-out look. Oil slicks are notoriously difficult to spot in natural-color (photo-like) satellite imagery because a thin sheen of oil only slightly darkens the already dark blue background of the ocean. Under unique viewing conditions, oil slicks can become visible in photo-like images, but usually, radar imagery is needed to clearly see a spill from space.

Ring of Fire

This new image from the Solar Dynamics Observatory’s Atmospheric Imaging Assembly (AIA) shows in great detail a solar prominence taken from a March 30, 2010 eruption. The twisting motion of the material is the most noticeable feature.
Launched on Feb. 11, 2010, SDO is the most advanced spacecraft ever designed to study the sun. During its five-year mission, it will examine the sun's magnetic field and also provide a better understanding of the role the sun plays in Earth's atmospheric chemistry and climate. Since launch, engineers have been conducting testing and verification of the spacecraft’s components. Now fully operational, SDO will provide images with clarity 10 times better than high-definition television and will return more comprehensive science data faster than any other solar observing spacecraft.

Durante sus dos décadas de existencia, el telescopio espacial Hubble ha conmovido y sorprendido, transformando nuestra forma de ver el universo.

El 25 de abril se cumplen 20 años desde que el Hubble fuera desplegado por la NASA, la agencia espacial estadounidense, a unos 600 kms de la Tierra.

Desde su posición privilegiada, por encima de la atmósfera, el telescopio ha sido nuestros ojos, asomándose a los lugares más remotos del cosmos.

La historia que cuentan sus imágenes, con colores y movimientos espectaculares, es tan dramática como la vida misma: nubes turbulentas que son cunas estelares, estrellas que al morir explotan y despiden su material, que algún día se transformará en otras estrellas o planetas en un proceso contínuo de regeneración.

Un proceso del que somos parte nosotros mismos.

El Dr. Francisco Diego, astrónomo del University College de Londres, nos da su visión personal del legado del Hubble en este video de BBC Mundo

The Birth of Stars
This new Hubble photo is but a small portion of one of the largest seen star-birth regions in the galaxy, the Carina Nebula. Towers of cool hydrogen laced with dust rise from the wall of the nebula. Reminiscent of Hubble's classic image of the Eagle Nebula dubbed the 'Pillars of Creation' this image is even more striking in appearance. Captured here are the top of a three-light-year-tall pillar of gas and the dust that is being eaten away by the brilliant light from nearby bright stars. The pillar is also being pushed apart from within, as infant stars buried inside it fire off jets of gas that can be seen streaming from towering peaks like arrows sailing through the air.

Hurricane Season 2010: Tropical Storm Sean (Southern Indian Ocean)


April 23, 2010
Cyclone 24S Now All Grown Up and Renamed "Tropical Storm Sean"
Weather systems that become tropical cyclones go through a couple of names before they mature, just like people with nicknames. Such is the case with Cyclone 24S in the Southern Indian Ocean that was just renamed Tropical Storm Sean.
When a weather system develops it is given a weather system number to keep track of it. For example, Sean was "born" as System 91S on April 21 about 630 nautical miles north-northwest of Port Hedland, Australia. On April 22, System 91S strengthened and developed tropical cyclone characteristics but wasn't quite a tropical storm, so it was renamed as the twenty-fourth tropical cyclone in the Southern Hemisphere, "Tropical Cyclone 24S." After strengthening further and reaching tropical storm status, it received a human name and became "Tropical Storm Sean." So, it went through two numbered nicknames to get its "grown-up name."
The Atmospheric Infrared Sounder (AIRS), instrument that flies aboard NASA's Aqua satellite from April 22 at 17:29 UTC (1:29 p.m. EDT) showed some strong, high, cold thunderstorms around Sean's center.
Infrared imagery is false-colored and higher cloud tops of stronger storms are depicted in purple. Sean showed a circular area of high, strong thunderstorms around his center of circulation. Those highest thunderstorms are as cold as or colder than 220 Kelvin or minus 63 degrees Fahrenheit (F).
On Friday, April 23 at 1500 UTC (11 a.m. EDT) Tropical Storm Sean had maximum sustained winds near 45 knots (52 mph). It was about 475 nautical miles north of Learmonth, Australia, near 14.4 South and 113.3 East. It was moving southeast at 4 knots (5 mph).
Animated infrared satellite imagery shows convective banding (that is, rapidly rising air that condenses and form thunderstorms) keeps wrapping into the low-level center of the storm, from both the south and east of the center. Forecasters at the Joint Typhoon Warning Center note that conditions are still good for further intensification over the next 12-24 hours, but then Sean will encounter vertical wind shear and begin weakening over the weekend.
Sean is a sea storm, and will not affect any land areas over the weekend.
