A squad of seals living off the coast of West Antarctica has provided scientists with data that could help to improve estimates of future sea-level rise. Researchers equipped the rolly-poly marine mammals with sensors that measured temperature and salinity in the Amundsen Sea. This remote and understudied patch of ocean could be accelerating the melt of the West Antarctic ice sheet, so year-round information on water conditions is key to predicting the ice sheet’s contribution to the world’s rising oceans.

An Antares rocket launched from Virginia this morning includes the Cold Atom Laboratory (CAL) that will chill atoms to just about absolute zero—colder than the vacuum of space itself, creating Bose-Einstein condensates on board the ISS.

“Essentially, it’s going to allow us to do different kinds of things than we’d be able to do on Earth,” Gretchen Campbell, co-director of the University of Maryland’s Joint Quantum Institute, told Gizmodo. “Whenever you have new capabilities, that will lead to new and exciting physics.”

The Square Kilometer Array, which will be the widest radio telescope array when it opens and one of the most precise when it begins operation in 2020, combining 250 dishes. "This next-generation facility will be the first telescope capable of detecting Earth-level leakage from nearby stars," says UC Berkeley SETI Research Center director Andrew Siemion.

For now, scientists in Hawaii and around the world are watching Kilauea and waiting to see what else the volcano will do. “This has so far been playing out how USGS said it would,” says Janine Krippner, a volcanologist at Concord University in Athens, West Virginia. “That itself is incredible.”

China has taken its first major step in a groundbreaking lunar mission. On 21 May, a probe launched from Xichang Space Centre to head beyond the Moon — where it will lie ready to act as a communications station for the Chang’e-4 lunar lander. The nation hopes that the Chang’e-4 lander will, later this year, become the first ever probe to touch down on the far side of the Moon.

In 100-Billion Years Accelerated Expansion --"Will Make It Appear That We're Alone in the Universe"


Potw1415a


If intelligent life re-emerges in our solar system in a few billion years, observes B. G. Buehler, only a few points of light will still be visible in the sky. What kind of theory of the universe will those beings concoct? It is almost certain to be wrong. Why do we think that what we can view now can lead us to a "correct" theory when a few billion years before us, things might have looked completely different?

"Kidnapped!" First Permanent Immigrant to Our Solar System was Captured By Jupiter's Gravitational Field

"Asteroid immigration from other star systems occurs because the Sun initially formed in a tightly-packed star cluster, where every star had its own system of planets and asteroids," says Dr. Helena Morais, an astronomer with São Paulo State University.

The Alien Observatory: "Signals of Extinct Extraterrestrial Civilizations --Echo Throughout the Milky Way"

“The signals will be from the civilization as it was,” said Frank Drake, creator of the famous Drake Equation. “It is not a remote possibility — it is a high probability — that signals we receive will be from a "civilization that no longer exists.”

"We learned from Kepler that there are more planets than stars in our sky, and now TESS will open our eyes to the variety of planets around some of the closest stars," Paul Hertz, the director of NASA's astrophysics division, said. "TESS will cast a wider net than ever before for enigmatic worlds."

Today's Top Space Headline --"We've Lost Contact!" --NASA's New Horizon's Mission to Pluto Was Nearly a Heartbreaker

"What made this even worse, was that every move had to be done by remote control with a nine-hour round-trip radio communication time between mission control and the spacecraft. Science classes teach how the speed of light is incredibly fast, how a signal moving at that speed can travel around the world in an eighth of a second or to the moon and back—a half-million-mile trip—in just two and a half seconds. But for the New Horizons team trying to get their spacecraft back on track as it closed in on Pluto, the great distance between Earth and New Horizons made the speed of light seem excruciatingly slow."
