Space Station Detector Finds Unexplained Positron Excess
6.10.2014

Where did all these high energy positrons come from? The Alpha Magnetic Spectrometer (AMS-02) onboard the International Space Station (ISS) has been meticulously recording how often it is struck by both high energy electrons and positrons since 2011.

An Ion Drive for Deep Space 1
20.07.2003

Space travel entered the age of the ion drive in 1998 with the launch of Deep Space 1, a NASA mission designed primarily to test new technologies. Although the ion drive on Deep Space...

A Space Station Crosses a Busy Sun
11.04.2022

Typically, the International Space Station is visible only at night. Slowly drifting across the night sky as it orbits the Earth, the International Space Station (ISS) can be seen as a bright spot several times a year from many locations.

Holometer: A Microscope into Space and Time
2.09.2014

How different are space and time at very small scales? To explore the unfamiliar domain of the miniscule Planck scale -- where normally unnoticeable quantum effects might become dominant -- a newly developed instrument called the Fermilab Holometer has begun operating at the Fermi National Accelerator Laboratory (Fermilab) near Chicago, Illinois, USA.

APOD: 2008 April 1- New Space Station Robot Asks to be Called Dextre the Magnificent
1.04.2008

In a surprising and potentially troubling request, the new space station robot known as Dextre demanded that astronauts refer to it in the future at "Dextre the Magnificent." Brandishing power tools that would make...

The Space Station Crosses a Spotless Sun
15.07.2019

That's no sunspot. It's the International Space Station (ISS) caught passing in front of the Sun. Sunspots, individually, have a dark central umbra, a lighter surrounding penumbra, and no solar panels. By contrast, the ISS is a complex and multi-spired mechanism, one of the largest and most sophisticated machines ever created by humanity.

All of These Space Images are Fake Except One
9.11.2021

Why would you want to fake a universe? For one reason -- to better understand our real universe. Many astronomical projects seeking to learn properties of our universe now start with a robotic telescope taking sequential images of the night sky.

Jupiter from the Webb Space Telescope
30.08.2022

This new view of Jupiter is illuminating. High-resolution infrared images of Jupiter from the new James Webb Space Telescope (Webb) reveal, for example, previously unknown differences between high-floating bright clouds -- including the Great Red Spot -- and low-lying dark clouds.

Aurora Australis and the International Space Station
13.09.2024

This snapshot from the International Space Station was taken on August 11 while orbiting about 430 kilometers above the Indian Ocean, Southern Hemisphere, planet Earth. The spectacular view looks south and east, down toward the planet's horizon and through red and green curtains of aurora australis.
