The physicist suggests that orbiting objects are stakes for Mars probes to observe the Earth

Discovery of pulsars The British astronomer Dame Jocelyn Bell Burnell was the first person to discover a pulsar in 1967 when she discovered a radio pulsar. Since then other types of pulsars emitting X-rays and gamma rays have also been discovered. Pulsars are essentially rotating, highly magnified neutron stars, but when discovered for the first time, they were thought to …

Near-Earth objects could be used by extraterrestrials 'to watch our world,' stunning study suggests

Although Earth only has one moon, it does have other natural satellites, including asteroid 2016 HO3, known as a "co-orbital object." These tiny celestial objects could be related to "attractive location for extraterrestrial intelligence." The research suggests that this space rocks could be grounds for an advanced civilization, given their small size and close proximity to the planet "These Near-Earth …

New laser vibration sensor detects buried objects from moving vehicles

The sensor is designed to improve detection of landmines and non-destructive testing. Detecting landmines can be a challenging and slow process. If captured by a moving vehicle, it would speed up the process, but at the expense of accuracy. At the Optical Society Laser Congress (OSA), held in Vienna, Austria from September 29 to October 3, 2019, researchers from the …

Tiny lensless endoscope captures 3-D images of objects smaller than a cell

Researchers have developed a new self-calibrating endoscope. Credit: J. Czarske, TU Dresden, Germany              Researchers have developed a new self-calibrating endoscope that produces 3-D images of objects smaller than a single cell. Without a lens or any optical, electrical or mechanical components, the tip of the endoscope measures just 200 microns across, about the width of a few human hairs …

These bizarre objects may have "supersaturated" supermassive black holes

Dark Stars Astronomers have set up a new theory for the formation of supermassive black holes. Extremely bright objects that appeared shortly before the birth of the universe – theoretical objects that are referred to as "dark stars" – could have seeded supermassive black holes over millions of years, according to a new astronomy story about physicist Katherine Freese of …

25 everyday objects that NASA invented

Contrary to popular belief, NASA invented neither Tang nor Klett – but there are many products, technologies, and other things that NASA invented everyday, from baby food to tires. Read on to see the everyday products invented by rocket scientists. Memory Foam Mattresses Temper Foam, also known as Memory Foam, was originally designed as a padding to improve the impact …
