Astronomers uncover new way to measure space’s expansion
2019年7月9日 · Over a period of months, the astronomers used the radio telescopes to measure the movement of a superfast jet of material ejected from the explosion. “We used these measurements along with detailed hydrodynamical simulations to determine the orientation angle, thus allowing use of the gravitational waves to determine the distance,” said ...
If a nuclear-powered spacecraft exploded in space, would it affect …
2015年3月3日 · An explosion like this is likely to cause a burst of X-rays and gamma rays. If these were to hit the Earth, they would be absorbed by our atmosphere, a protective barrier that also does a good job of absorbing harmful radiation from the Sun.
Apollo 11’s manned lunar landing was almost cancelled, says Buzz …
“What had been happening in the evolution of Apollo was that Apollo 11, when it was assigned its crew, was potentially going to be the first landing mission. However, I’ve recently learned from the programme manager Hugh Davis that Lunar Excursion Module 5 [LEM 5, the Apollo 11 Eagle lunar lander], which was scheduled to fly on Apollo 11 ...
Heroes of Space: Michael Collins
Following this mission he was selected as the Command Module pilot for Apollo 11, which meant he remained in orbit around the moon while Armstrong and Aldrin landed on the surface. In a series of questions and answers prepared for the 40th anniversary of Apollo 11’s mission in 2009, Collins alluded to a feeling of worry for his crewmates ...

Curiosity measures a Martian mountain’s gravity
2019年2月1日 · Side-by-side images depict NASA’s Curiosity rover (left) and a moon buggy driven during the Apollo 16 mission. Image credit: NASA/JPL-Caltech The results were also compared to mineral-density estimates from Curiosity’s Chemistry and Mineralogy instrument, which characterises the crystalline minerals in rock samples by using an X-ray beam.
Amazing image of the penultimate lunar landing blasting off
2012年5月3日 · Apollo 16 was the fifth of six successful US missions to the moon, with Apollo 13 being the only one that failed to perform a lunar landing as intended. It was the only mission to touch down in the highlands of the moon, where samples from what were thought to be previously volcanic regions were taken, although this was later proved incorrect ...
Hubble sees prolonged death of exploding star - All About Space
The explosion is the result of a thermonuclear chain reaction, which produces a large amount of heavy elements. The light that researchers see when a type Ia supernova explodes comes from the radioactive decay of an isotope of nickel (56Ni) into an isotope of cobalt (56Co) and then into a stable isotope of iron (56Fe).
Film Review: First Man
As a fan of both film and space exploration, this film is a winner. With big names such as director Damien Chazelle and Ryan Gosling portraying Neil Armstrong, the film is not only dramatic and thrilling, but its accuracy of events, locations, equipment, rockets and the actual Apollo 11 Moon landing itself is phenomenal.
