Our solar system’s first known interstellar object gets unexpected speed boost

Using observations from NASA's Hubble Space Telescope and ground-based observatories, an international team of scientists have confirmed ?Oumuamua (oh-MOO-ah-MOO-ah), the first known interstellar object to travel through our solar system, got an unexpected boost in speed and shift in trajectory as it passed through the inner solar system last year. "Our high-precision measurements of ?Oumuamua's position revealed that there was something affecting its motion other…

SwRI scientists find evidence of complex organic molecules from Enceladus

SAN ANTONIO -- June 27, 2018 -- Using mass spectrometry data from NASA's Cassini spacecraft, scientists found that large, carbon-rich organic molecules are ejected from cracks in the icy surface of Saturn's moon Enceladus. Southwest Research Institute scientists think chemical reactions between the moon's rocky core and warm water from its subsurface ocean are linked to these complex molecules. "We are, yet again, blown away…

Granite crystallizes at temperature 200 degrees lower than previously thought

IMAGE: The gradient of titanium in quartz is evidence that the mineral crystallized at a cooler temperature than had been previously believed. view more  Credit: Rensselaer Evidence from rocks in Yosemite National Park suggests that granite stored in the Earth's crust is partially molten at 500 degrees Celsius, nearly 200 degrees lower than had previously been believed. The finding, published online today in Nature, challenges long-held…

Sandbox craters reveal secrets of planetary splash marks and lost meteorites

Look up above you. You might see blue sky, clouds, the Moon or stars. And while it might seem calm up there, the truth is it's nearly always raining. Every day, Earth is constantly bombarded by about 100 tons of falling objects from space, mostly simple dust or sand-sized particles that are destroyed as they hit the upper atmosphere. But very rarely, a piece large…

Historic growth in impact factors for Mary Ann Liebert, Inc. journals

New Rochelle, NY, June 26, 2018-- Mary Ann Liebert, Inc., publishers announces significant growth in the impact factors of its peer-reviewed journals, as reported in the new Journal Citation Reports (Clarivate Analytics, 2018). More than 50% of the company's portfolio of previously indexed journals saw double-digit percentage increases in impact factors, including Thyroid with a 37% increase and new impact factor of 7.557; AIDS Patient…

NASA catches a view of a fading Tropical Cyclone Daniel

Twelfth impact structure discovered in Central Finland

The crater has a diameter of 2.6 km and it is covered by the Lake Summasjärvi (Summanen), about 9 km south-east of the nearest city, Saarijärvi, and 275 km north of Helsinki. The age of the impact event and the type of the meteorite causing the crater, are still unknown. The discovery is based on earlier geophysical studies of the area by Geological Survey of…
