    Asteroid to Fly Safely Past Earth on April 19

    April 9, 2017, Categories  Astronomy/Space

    This computer-generated image depicts the flyby of asteroid 2014 JO25. The asteroid will safely fly past Earth on April 19 at a distance of about 1.1 million miles (1.8 million kilometers), or about 4.6 times the distance between Earth and the moon. Credit: NASA/JPL-Caltech

    A relatively large near-Earth asteroid discovered nearly 3 years ago will fly safely past Earth on April 19 at ~1.1 million miles or ~4.6 times the distance from Earth to the moon. Although there is no possibility for the asteroid to collide with our planet, this will be a very close approach for an asteroid of this size...

    Dramatic Stellar fireworks of Star Birth

    April 8, 2017, Categories  Astronomy/Space

    Astronomers captured these dramatic images of the remains of a 500-year-old explosion as they explored the firework-like debris from the birth of a group of massive stars, demonstrating that star formation can be a violent and explosive process too. The colors in the ALMA data represent the relative Doppler shifting of the millimeter-wavelength light emitted by carbon monoxide gas. The blue color in the ALMA data represents gas approaching at the highest speeds; the red color is from gas moving toward us more slowly. The background image includes optical and near-infrared imaging from both the Gemini South and ESO Very Large Telescope. The famous Trapezium Cluster of hot young stars appears towards the bottom of this image. The ALMA data do not cover the full image shown here. Credit: ALMA (ESO/NAOJ/NRAO), J. Bally/H. Drass et al

    1st time Atmosphere Spotted on Nearly Earth-Size Exoplanet

    The exoplanet GJ 1132b, which orbits the dwarf star GJ 1132, is located about 39 light-years away from Earth. It has a radius about 1.4 times that of Earth and is 1.6 times Earth’s mass, according to the new study. When the planet was first discovered, researchers called it a potential Venus twin because it’s a rocky world with a very high surface temperature — and now, they’ve found that the planet and Venus might have a thick atmosphere in common, too (although it would have a different composition).

    While observers have pinpointed atmospheres around much larger, Jupiter-like gas giants orbiting other stars — and a larger ...

    Hubble takes Close-up Portrait of Jupiter

    April 7, 2017, Categories  Astronomy/Space

    This dazzling Hubble Space Telescope photo of Jupiter was taken when it was comparatively close to Earth, at a distance of 415 million miles. Hubble reveals the intricate, detailed beauty of Jupiter's clouds as arranged into bands of different latitudes, known as tropical regions. These bands are produced by air flowing in different directions at various latitudes. Lighter colored areas, called zones, are high-pressure where the atmosphere rises. Darker low-pressure regions where air falls are called belts. The planet's trademark, the Great Red Spot, is a long-lived storm roughly the diameter of Earth. Much smaller storms appear as white or brown-colored ovals. Such storms can last as little as a few hours or stretch on for centuries. Credit: NASA, ESA, and A. Simon (NASA Goddard)
