Models suggest subglacial river flows entire length of Greenland’s ice sheet

Nov. 12 (UPI) — New analysis suggests a valley stretching the length of Greenland’s ice sheet might allow meltwater from the continent’s interior to flow hundreds of miles toward an outlet at Petermann Fjord, positioned on the island’s northern coast.

For years, scientists have been working hard to map the contours of Greenland’s bedrock, which lies beneath thousands of feet of ice.

“It is an extremely hard to observe environment,” Chris Chambers, researcher at Hokkaido University’s Institute of Low Temperature Science, told UPI in an email.

Over the years, scientists have built a relatively detailed map of the continent’s bedrock — and the shape of the ice sheet’s underbelly — by piecing together radar scans captured research aircraft.

Unfortunately, the process of stitching together dozens of radar scans leaves lots of small gaps in the data. Researchers typically rely on mathematical models to fill these gaps.

“The data gaps are

Comsat Architects of Rocky River awarded $250,000 grant; could be just the beginning

ROCKY RIVER, Ohio – Comsat Architects in Rocky River specialize in space communication technology. The firm has been awarded a $250,000 grant from the National Science Foundation (NSF) Small Business Innovation Research—known as the Phase I Seed Fund.

Comsat Architects, an engineering service, was founded in 2014 with the goal of enhancing the communication between Earth and space equipment such as satellites, landers and rovers. The company’s motto is, “Connecting Earth to the Moon and Beyond.”

The purpose of the NSF grant is to conduct research and development work on “a comprehensive cognitive communications payload module to enhance communications functions for groups of small satellites called CubeSats.”

The module has several applications that include Earth observation as well as science and space communications, according to NSF. In addition, the module will be involved in data transmission for commercial, government and academic uses.

“It is an honor that NSF chose to

Astronomer Names Massive, Mysterious Hydrogen Trail After Colombia’s Famous River

A Colombian astronomer has named what could be the largest known coherent object in our galaxy after Colombia’s Magdelena river, made famous in the pages of “Love in the Time of Cholera” by Gabriel Garcia Marquez.

Juan Diego Soler, a Colombian astrophysicist at the Max Planck Institute for Astronomy in Germany, and his colleagues announced in late October that they’d found a 3000 light-years-long “lane” of atomic hydrogen that Soler named “Magdelena” in honor of his home country’s most culturally and economically important waterway

“It is the first time that I get to name an astronomical object,” he said, “That river is the real heart of Colombia and I hope to remind all Colombians of what a fantastic treasure we have in our country.”

Soler, who studies the formation of stars, says the formation,
