In space, things don’t always behave the way we expect them to. In the case of cancer, researchers have found that this is a good thing: some tumors seem to be much less aggressive in the microgravity environment of space compared to their behavior on Earth. This observation could help scientists understand the mechanism involved and develop drugs targeting tumors that don’t respond to current treatments. This work is the latest in a large body of evidence on how space exploration benefits those of us on Earth. This image is of a thyroid cancer cell line FTC-133 after four hours of exposure to simulated microgravity. Nuclei are stained blue, components of the cytoskeleton stained green and red.

Off into space - A set of NanoRacks CubeSats is photographed by an Expedition 38 crew member after deployment by the NanoRacks Launcher attached to the end of the Japanese robotic arm. The CubeSats program contains a variety of experiments such as Earth observations and advanced electronics testing. International Space Station solar array panels are at left. Earth's horizon and the blackness of space provide the backdrop for the scene. Two sets of CubeSats were deployed late Wednesday, Feb. 26, and early Thursday, Feb. 27, leaving just two more launches to go of the 33 CubeSats that were delivered to the station in January by Orbital Sciences’ Cygnus cargo ship. The latest CubeSats were sent on their way at 8:50 p.m. EST Wednesday and 2:40 a.m. Thursday. CubeSats are a class of research spacecraft called nanosatellites and have small, standardized sizes to reduce costs. Two final batches of CubeSats are set for deployment at 11:20 p.m. Thursday and 2:30 a.m. Friday, but more are scheduled to be delivered to the station on the second Orbital commercial resupply mission in May.

The closest supernova of its kind to be observed in the last few decades has sparked a global observing campaign involving legions of instruments on the ground and in space, including NASA's Spitzer Space Telescope and Hubble Space Telescope. Seen here is supernova explosion SN 2014J in the galaxy M82 from these two different spacecraft. As a distance of approximately 11.5 million light-years from Earth, galaxy M82 is seen by the Hubble Space Telescope in the background of this composite image. Astronomers using a ground-based telescope discovered the explosion on January 21, 2014. On the left is Spitzer's view of the supernova on three separate dates: May 9, 2005; Feb. 7, 2014; and Feb. 12, 2014. The observations from February 7 reveal the presence of a bright spot -- the supernova -- not present in the prior observations. By Feb. 12, the supernova has started to dim somewhat from its peak brightness in the first week of February. The supernova is glowing very brightly in the infrared light that Spitzer sees. The telescope was able to observe the supernova before and after it reached its peak brightness. Such early observations with an infrared telescope have only been obtained for a few Type Ia supernovas in the past. On the right is the supernova seen by Hubble on Jan. 31, 2014 as the supernova approached its peak brightness. The Hubble image was taken in visible light with Hubble's Wide Field Camera 3.

NASA's Kepler mission announced Wednesday the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system. Nearly 95 percent of these planets are smaller than Neptune, which is almost four times the size of Earth. This discovery marks a significant increase in the number of known small-sized planets more akin to Earth than previously identified exoplanets, which are planets outside our solar system. The artist concept depicts multiple-transiting planet systems, which are stars with more than one planet. The planets eclipse or transit their host star from the vantage point of the observer. This angle is called edge-on. Image Credit: NASA #kepler #planets #exoplanets #solarsystem #newworlds #newplanets #science #discovery; -
On Feb. 19, 2014 the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite flew over the Great Lakes and captured this striking false-colored image of the heavily frozen Great Lakes – one of the hardest freeze-ups in four decades. According to the National Oceanic and Atmospheric Administration (NOAA) Great Lakes Environmental Research Laboratory (GLERL), ice cover on North America’s Great Lakes peaked at 88.42% on Feb. 12-13 – a percentage not recorded since 1994. The ice extent has surpassed 80% just five times in four decades. The average maximum ice extent since 1973 is just over 50%. Unusually cold temperatures in the first two months of the year, especially in January, are responsible for the high ice coverage. Very cold air blowing over the surface of the water removes heat from the water at the surface. When the surface temperature drops to freezing, a thin layer of surface ice begins to form. Once ice formation begins, persistently cold temperatures, with or without wind, is the major factor in thickening ice. This false-color image uses a combination of shortwave infrared, near infrared and red (MODIS bands 7,2,1) to help distinguish ice from snow, water and clouds. Open, unfrozen water appears inky blue-black. Ice is pale blue, with thicker ice appearing brighter and thin, melting ice appearing a darker true-blue. Snow appears blue-green. Clouds are white to blue-green, with the colder or icy clouds appearing blue-green to blue.

First Moments of a Solar Flare in Different Wavelengths of Light - On Feb. 24, 2014, the sun emitted a significant solar flare, peaking at 7:49 p.m. EST. NASA's Solar Dynamics Observatory (SDO), which keeps a constant watch on the sun, captured images of the event. These SDO images from 7:25 p.m. EST on Feb. 24 show the first moments of this X-class flare in different wavelengths of light -- seen as the bright spot that appears on the left limb of the sun. Hot solar material can be seen hovering above the active region in the sun's atmosphere, the corona. Solar flares are powerful bursts of radiation, appearing as giant flashes of light in the SDO images. 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.

We’re getting ready to lift off Thursday! The launch pads at the Japan Aerospace Exploration Agency’s (JAXA) Tanegashima Space Center on Tanegashima Island, Japan, are seen on Friday, Feb. 21, 2014, a week ahead of the planned launch of an H-IIA rocket carrying the Global Precipitation Measurement (GPM) Core Observatory. GPM is an international mission led by NASA and JAXA to measure rain and snowfall over most of the globe multiple times a day. To get that worldwide view of precipitation, multiple satellites will be contributing observations for a global data set, all unified by the advanced measurements of GPM's Core Observatory, built at NASA's Goddard Space Flight Center in Greenbelt, Md. Launch of the GPM Core Observatory from Tanegashima Space Center is scheduled for Thursday, Feb. 27, during a window beginning at 1:07 p.m. EST (3:07 a.m. on Friday, Feb. 28 Japan time).
