The Physics of Failure: Analyzing Hubble’s Gyroscope Malfunction

Posted by in categories: health, physics, space

The Hubble Space Telescope is currently in safe mode due to gyroscope problems, suspending its science activities. However, NASA remains optimistic about its future contributions to space exploration, working in tandem with other telescopes.

On May 24, NASA’s Hubble Space Telescope entered safe mode due to an ongoing gyroscope (gyro) issue, suspending science operations. Hubble’s instruments remain stable, and the telescope is in good health.

The telescope automatically entered safe mode when one of its three gyroscopes returned faulty telemetry readings. Hubble’s gyros measure the telescope’s slew rates and are part of the system that determines and controls precisely the direction the telescope is pointed.

Strange Radio Signal From Deep Space Baffles Scientists

Posted by in category: space

We’ve received a strange signal from across the galaxy, and astronomers are struggling to understand what it means.

They know what’s emitting the signals. It’s a neutron star named ASKAP J193505.1+214841.0 (ASKAP J1935+2148 for short), located in the plane of the Milky Way, some 15,820 light-years from Earth.

But the signals themselves are like none we’ve ever seen before. The star goes through periods of strong pulses, periods of weak pulses, and periods of no pulses at all.

NASA’s Juno provides High-Definition views of Europa’s Icy Shell

Posted by in category: space

Images from the JunoCam visible-light camera aboard NASA’s Juno spacecraft supports the theory that the icy crust at the north and south poles of Jupiter’s moon Europa is not where it used to be. Another high-resolution picture of the icy moon, by the spacecraft’s Stellar Reference Unit (SRU), reveals signs of possible plume activity and an area of ice shell disruption where brine may have recently bubbled to the surface.

The JunoCam results recently appeared in the Planetary Science Journal and the SRU results in the journal JGR Planets.

On Sept. 29, 2022, Juno made its closest flyby of Europa, coming within 220 miles (355 kilometers) of the moon’s frozen surface. The four pictures taken by JunoCam and one by the SRU are the first high-resolution images of Europa since Galileo’s last flyby in 2000.

Study of photons in quantum computing reveals that when photons collide, they create vortices

Vortices are a common physical phenomenon. You find them in the structure of galaxies, tornadoes and hurricanes, as well as in a cup of tea, or water as it drains from the bathtub.

“Extraordinary” Slow-Spinning Neutron Star Shakes Astrophysics

Posted by in categories: physics, space

Most collapsed stars fully rotate in seconds. This one takes almost an hour.

Australian scientists from the University of Sydney and Australia’s national science agency, CSIRO, have detected what is likely a neutron star spinning slower than any other ever measured.

No other radio-emitting neutron star, out of the more than 3,000 discovered so far, has been discovered rotating so slowly. The results are published today (June 5) in Nature Astronomy.

Scientists Intrigued By Almost Perfectly Circular Pit on the Surface of Mars

Posted by in category: space

Link :


NASA’s Mars Reconnaissance Orbiter (MRO) has discovered another intriguing formation on the planet’s barren surface.

As spotted by Universe Today, the spacecraft captured this image of a satisfyingly circular pit — and what its dark, yawning entrance leads to remains a question high on the minds of Mars scientists.
