NASA’s Juno back to normal operations after entering safe mode

Data received from NASA’s Juno mission indicates the solar-powered spacecraft went into safe mode twice on April 4 while the spacecraft was flying by Jupiter. Safe mode is a precautionary status that a spacecraft enters when it detects an anomaly. Nonessential functions are suspended, and the spacecraft focuses on essential tasks like communication and power management. Upon entering safe mode, Juno’s science instruments were powered down, as designed, for the remainder of the flyby.

How you can observe impacts on Jupiter

Lucky is the word I’d use for any telescopic observers who got to see one of the most stunning spectacles in nature when Comet Shoemaker-Levy 9 impacted Jupiter in July 1994. The collision left inky scars in the planet’s atmosphere that persisted for months, with the largest welts visible in even the smallest of telescopes.Continue reading “How you can observe impacts on Jupiter” The post How you can observe impacts on Jupiter appeared first on Continue ReadingHow you can observe impacts on Jupiter

‘Hidden galaxies’ could be smoking gun in universe riddle

Astronomers have peered back in time to find what looks like a population of “hidden” galaxies that could hold the key to unlocking some of the universe’s secrets. If their existence is confirmed it would “effectively break current models of galaxy numbers and evolution.” The possible galaxies may also provide the missing piece of the puzzle for the energy generation in the universe in infrared light.

X-ray binary 4U 1907+09: NuSTAR observations reveal flux variability and spin-down

Using NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), Indian astronomers have performed X-ray observations of an X-ray binary designated 4U 1907+09. Results of the observational campaign, published April 3 on the arXiv preprint server, yield new insights into the variability of this source, shedding more light on its nature.
