The next big NASA rocket has arrived

It’s a make-or-break moment for NASA’s next mega-rocket: the Space Launch System. Why it matters: The rocket – about 10 years in development and billions of dollars over budget – is expected to launch for the first time this year. Its success is the key to NASA’s plans to bring people and payloads to deep space destinations like the Moon. …

Strange FM signal detected coming from one of Jupiter’s moons

NASA recently extended the life of two of its planetary discovery missions, including the Juno mission to Jupiter. Now it has come to light that Juno has discovered an FM signal originating from one of the gas giant’s moons, Ganymede. The discovery is not an indication of extraterrestrial life, but it is nonetheless fascinating as it is the first time …

Measurements of pulse acceleration reveal the dark side of the Milky Way

The ripples in the Milky Way disk are displayed along with the tidal remnants of Sagittarius’ dwarf galaxy. The pulsars analyzed by Chakrabarti et al 2021 for calculating galactic accelerations are shown in the effort. Credit: IAS; Dana Berry It is well known that the expansion of the universe is accelerating due to a mysterious dark energy. Within galaxies, stars …
