NASA’s Hubble Spots Possible Water Plumes Erupting on Jupiter's Moon Europa

New findings from NASA's Hubble Space Telescope show suspected water plumes erupting from Jupiter's icy moon Europa. These observations bolster earlier Hubble work suggesting that Europa is venting water vapor. A team of astronomers, led by William Sparks of the Space Telescope Science Institute in Baltimore, observed these finger-like projections while viewing Europa's limb as the moon passed in front of Jupiter. The study will be published on Sept. 29 in The Astrophysical Journal.

Revealing Earth’s Early Secrets: Scientists Uncover Insights Into the Formation of Earth’s Oldest Continental Crust

P1130482.jpg

Addressing fundamental unknowns about the earliest history of Earth’s crust, scientists have precisely dated the world’s oldest rock unit at 4.02 billion years old. Driven by the University of Alberta, the findings suggest that early Earth was largely covered with an oceanic crust-like surface.

Hubble Takes Close-Up Look at Disintegrating Comet

Astronomers have captured the sharpest, most detailed observations of a comet breaking apart 67 million miles from Earth, using NASA's Hubble Space Telescope. This study of Comet 332P is published online in The Astrophysical Journal Letters.

All Polar Bears Across the Arctic Face Shorter Sea Ice Season

A new University of Washington study finds a trend toward earlier sea ice melt in the spring and later ice growth in the fall across all 19 polar bear populations, which can negatively impact the feeding and breeding capabilities of the bears. The paper is the first to quantify the sea ice changes in each polar bear subpopulation across the entire Arctic region using metrics that are specifically relevant to polar bear biology.

Chemistry Says Moon Is Proto-Earth’s Mantle, Relocated

Wang_Jacobsen_Nature2016-11.jpg

The leading theory for the moon's formation got in trouble recently when it was revealed that the moon and Earth are isotopic twins. Now highly precise measurements of the isotopes of an element that was still condensed at the "cut off" temperature when material started to fall back to Earth suggest a dramatic solution to the problem.

Brown Dwarfs Hiding in Plain Sight in Our Solar Neighborhood

Cool brown dwarfs are a hot topic in astronomy right now. Smaller than stars and bigger than giant planets, they hold promise for helping us understand both stellar evolution and planet formation. New work from a team including Carnegie's Jonathan Gagné has discovered several ultracool brown dwarfs in our own solar neighborhood. Their findings are published in The Astrophysical Journal.

Genetics of African Khoesan Populations Maps to Kalahari Desert Geography

Geography and ecology are key factors that have influenced the genetic makeup of human groups in southern Africa, according to new research discussed in the journal GENETICS, a publication of the Genetics Society of America. By investigating the ancestries of twenty-two KhoeSan groups, including new samples from the Nama and the ≠Khomani, researchers conclude that the genetic clustering of southern African populations is closely tied to the ecogeography of the Kalahari Desert region.

Milky Way Had a Blowout Bash 6 Million Years Ago

122775_web.jpg

The center of the Milky Way galaxy is currently a quiet place where a supermassive black hole slumbers, only occasionally slurping small sips of hydrogen gas. But it wasn't always this way. A new study shows that 6 million years ago, when the first human ancestors known as hominins walked the Earth, our galaxy's core blazed forth furiously. The evidence for this active phase came from a search for the galaxy's missing mass.
