NASA measures 10 days of US extreme precipitation from space

From Jan. 25 through Feb. 3, IMERG data estimated that the most extreme precipitation over the United States during this period was over 200mm (7.9 inches) in an area where stormy weather frequently hit Mississippi and Alabama.For more than a week the weather over the continental United States has been punctuated by extreme events. NASA analyzed satellite data that measured the heavy precipitation over ten days...

The frigid Flying Saucer

<p>The young star 2MASS J16281370-2431391 lies in the spectacular Rho Ophiuchi star formation region, about 400 light-years from Earth. It is surrounded by a disc of gas and dust -- such discs are called protoplanetary discs as they are the early stages in the creation of planetary systems. This particular disc is seen nearly edge-on, and its appearance in visible light pictures has led to its being nicknamed the Flying Saucer.

<p>The main image shows part of the Rho Ophiuchi region and a much enlarged close-up infrared view of the Flying Saucer from the NASA/ESA Hubble Space Telescope is shown as an insert.The international team, led by Stephane Guilloteau at the Laboratoire d'Astrophysique de Bordeaux, France, measured the temperature of large dust grains around the young star 2MASS J16281370-2431391 in the spectacular...

Phase of the moon affects amount of rainfall

Satellite data over the tropics, between 10 degrees S and 10 degrees N, shows a slight dip in rainfall when the moon is directly overhead or underfoot. The top panel shows the air pressure, the middle shows the rate of change in air pressure, and the bottom shows the rainfall difference from the average. The change is 0.78 micrometers, or less than one ten thousandth of an inch, per hour.When the moon is high in the sky, it creates bulges in the planet's atmosphere that creates imperceptible changes in the amount of rain that falls below.

Hubble sees monstrous cloud boomerang back to our galaxy

Hubble Space Telescope astronomers are finding that the old adage 'what goes up must come down' even applies to an immense cloud of hydrogen gas outside our Milky Way galaxy. The invisible cloud is plummeting toward our galaxy at nearly 700,000 miles per hour.Hubble Space Telescope astronomers are finding that the old adage "what goes up must come down" even applies to an immense cloud of hydrogen gas outside our Milky Way galaxy....

Stellar parenting: Making new stars by 'adopting' stray cosmic gases

This is a portrait of the massive globular cluster NGC 1783 in the Large Magellanic Cloud, taken by the Hubble Space Telescope. This dense swarm of stars is located about 160,000 light years from Earth and has the mass of about 170,000 Suns. A new study by astronomers from the Kavli Institute for Astronomy and Astrophysics at Peking University (KIAA), the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), Northwestern University and the Adler Planetarium suggests the globular cluster swept up stray gas and dust from outside the cluster to give birth to three different generations of stars.Among the most striking objects in the universe are glittering, dense swarms of stars known as globular clusters. Astronomers had long thought globular clusters formed their millions of stars in...

Signs of second largest black hole in the Milky Way

Molecular clouds scattered by an intermediate black hole show very wide velocity dispersion. This scenario well explains the observational features of a peculiar molecular cloud CO-0.40-0.22.A team of astronomers led by Tomoharu Oka, a professor at Keio University in Japan, has found an enigmatic gas cloud, called CO-0.40-0.22, only 200 light years away from the...

Discovery: Most-luminous ever supernova

A team of astronomers, including Carnegie's Benjamin Shappee, Nidia Morrell, and Ian Thompson, has discovered the most-luminous supernova ever observed, called ASAS-SN-15lh. It is two times more luminous than any supernova previously discovered. In fact, ASAS-SN-15lh at peak was almost 50 times more luminous than the entire Milky Way galaxy. This is a comparison between a false-color pre-explosion image from the Dark Energy Survey and false-color follow-up image from the LCOGT 1-m network, courtesy of Benjamin Shappee.A team of astronomers, including Carnegie's Benjamin Shappee, Nidia Morrell, and Ian Thompson, has discovered the most-luminous supernova ever observed, called ASAS-SN-15lh.

Earth-like planets have Earth-like interiors

This artist's illustration compares the interior structures of Earth (left) with the exoplanet Kepler-93b (right), which is one and a half times the size of Earth and 4 times as massive. New research finds that rocky worlds share similar structures, with a core containing about a third of the planet's mass, surrounded by a mantle and topped by a thin crust.Every school kid learns the basic structure of the Earth: a thin outer crust, a thick mantle, and a Mars-sized core. But is this structure universal? Will rocky exoplanets orbiting...

Galactic center's gamma rays unlikely to originate from dark matter, evidence shows

Studies by two independent groups from the US and the Netherlands indicate that the observed excess of gamma rays from the inner galaxy likely comes from a new source rather than from dark matter. The best candidates are rapidly rotating neutron stars, which will be prime targets for future searches. The Princeton/MIT group and the Netherlands-based group used two different techniques, non-Poissonian noise and wavelet transformation, respectively, to independently determine that the gamma ray signals were not due to dark matter annihilation.Bursts of gamma rays from the center of our galaxy are not likely to be signals of dark matter but rather other astrophysical phenomena such as fast-rotating stars called millisecond...

First light for future black hole probe

<p>As part of the first observations with the new GRAVITY instrument the team looked closely at the bright, young stars known as the Trapezium Cluster, located in the heart of the Orion star-forming region. Already, from these first data, GRAVITY made a discovery: one of the components of the cluster (Theta1 Orionis F) was found to be a double star for the first time. The brighter double star Theta1 Orionis C is also well seen.
