Systems of tiny robots may someday build high-performance structures, from airplanes to space settlements
Hubble observes 1st confirmed interstellar comet
NASA’s Hubble Space Telescope has given astronomers their best look yet at an interstellar visitor — comet 2I/Borisov — whose speed and trajectory indicate it has come from beyond our solar system. This Hubble image, taken on Oct. 12, 2019,…
Radiation detector with the lowest noise in the world boosts quantum work
The nanoscale radiation detector is a hundred times faster than its predecessors, and can function without interruption
NRL launches space weather instrument on NASA satellite
WASHINGTON — A U.S. Naval Research Laboratory (NRL) instrument aboard NASA’s Ionospheric Connection Explorer (ICON) satellite will deliver unprecedented information to help scientists investigate how both terrestrial and solar weather impact the ionosphere, the ionized region of Earth’s upper atmosphere.…
New research sheds light on the ages of lunar ice deposits
The discovery of ice deposits in craters scattered across the Moon’s south pole has helped to renew interest in exploring the lunar surface, but no one is sure exactly when or how that ice got there. A new study suggests…
Technology to use hot air balloons for rocket launches competes in a startup battlefield
WEST LAFAYETTE, Ind. – Leo Aerospace, a Purdue University-affiliated startup looking to launch rockets with the help of hot air balloons, has taken to the technology battlefield to receive worldwide attention for its technology. Members of the Leo team took…
Pressure runs high at edge of solar system
Out at the boundary of our solar system, pressure runs high. This pressure, the force plasma, magnetic fields and particles like ions, cosmic rays and electrons exert on one another when they flow and collide, was recently measured by scientists…
Scientists observe year-long plateaus in decline of type Ia supernova light curves
This is a surprising finding as astronomers had expected that the light curve would not only continue decreasing but even experience a sharp drop, rather than flattening into a plateau. The discovery is a huge step forward for astronomers as…
A dusty lab in the sky
Joe Nuth loves dust. Among astronomers, that puts him in a minority. “The traditional astronomers — the people looking at galaxies and stars — they hate dust,” said Nuth, a planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt,…
NASA selects Illinois professor for satellite mission concept study
Lara Waldrop, assistant professor electrical and computer engineering at the University of Illinois at Urbana-Champaign has been selected by NASA to lead a multi-institution team to conduct a concept study for a satellite mission. Her mission, titled “Global Lyman-alpha Imagers…
A filament fit for space — silk is proven to thrive in outer space temperatures
Their initial discovery had seemed like a contradiction because most other polymer fibres embrittle in the cold. But after many years of working on the problem, the group of researchers have discovered that silk’s cryogenic toughness is based on its…
Teams of mobile 3D printing robots could fix bridges on Earth and build them to Mars
BROOKLYN, New York, Wednesday, October 2, 2019 – Commercial 3D printing — or additive manufacturing (AM) — is a booming industry. But if printers were liberated from the typical setup involving an immobile box and a gantry, and set free…

Trained at the University of Tromsø (Norway) and recruited at the Laboratory of Plasma Physics (CNRS/Ecole polytechnique/Observatoire de Paris/Université Paris-Sud/Sorbonne Université), Ane Aanesland, a CNRS researcher, is currently President and CEO of ThrustMe, a startup specialising in the propulsion of…
Saturn’s rings shine in Hubble’s latest portrait
Saturn is so beautiful that astronomers cannot resist using the Hubble Space Telescope to take yearly snapshots of the ringed world when it is at its closest distance to Earth. These images, however, are more than just beauty shots. They…
