Stellar stream of galaxy NGC 5907 has a morphology different than previously thought

Using Dragonfly Telephoto Array, astronomers have revisited the spiral galaxy NGC 5907 and provided more insights into the morphology of its stellar stream. The new observations indicate that this feature has a qualitatively different morphology than when it was observed about a decade ago. The new findings are reported in a paper published June 26 on arXiv.org. Source: https://phys.org/news/2019-07-stellar-stream-galaxy-ngc-morphology.html…

Landing the Mars 2020 rover: Autopilot will avoid terrain hazards autonomously

The view of the Sea of Tranquility rising up to meet Neil Armstrong during the first astronaut landing on the Moon was not what Apollo 11 mission planners had intended. They had hoped to send the lunar module Eagle toward a relatively flat landing zone with few craters, rocks and boulders. Instead, peering through his small, triangular commander’s window, Armstrong saw…

Learning how to protect astronauts from space radiation

There is little known about the effects of space radiation on the human body. Astronauts cannot see or feel it, yet the high doses they are exposed to outside Earth’s cocoon pose health hazards for trips to the Moon and Mars. To help investigate and find out more, European scientists can now accelerate atoms at close to the speed of light…
