Rotation Period

A fluid study homes in on the best method to make a cup of coffee, scientists use the Hubble Telescope to reassess the length of a day on Uranus, and we discuss more of the latest in science in this news roundup.

The rotation period of Uranus was estimated to be 17.24 hours in 1986 from radio auroral measurements made by NASA's Voyager 2 spacecraft.

Thanks to the Hubble Space Telescope, we now know that a day on Uranus lasts for 28 seconds longer than previously thought - a difference that could be crucial in planning future missions to the gas giant

XX Trianguli, a bright K0-type giant star in a binary system located in the constellation of Triangulum, exhibits chaotic, non-periodic star spot behavior.

Scientists think the giant exoplanet J1407b has a massive ring system much larger than Saturn's. A new study suggests the rings may orbit the planet backward. The post Do the giant rings of exoplanet J1407b rotate backward? first appeared on EarthSky.

Inspired by the half-human, half-horse creatures that are part of Ancient Greek mythology, the field of astronomy has its own kind of centaurs: distant objects orbiting the Sun between Jupiter and Neptune. NASA's James Webb Space Telescope has mapped the gases spewing from one of these objects, suggesting a varied composition and providing new insights […]

Scientists used the CHARA Array atop Mount Wilson in California to resolve previously unknown features of the North Star.

Interest in Earth-like planets orbiting within the habitable zone of their host stars has surged, driven by the quest to discover life beyond our solar system. But the habitability of such planets, known as exoplanets, is influenced by more than just their distance from the star.

UC Riverside astrophysicist Stephen Kane had to double-check his calculations. He wasn't sure the planet he was studying could be as extreme as it seemed.

NASA's Jet Propulsion Laboratory used a powerful Deep Space Network radar antenna to image asteroid 2008 OS7 as it spun harmlessly past Earth on Feb. 2, 2024...

Uranus and Neptune, the two outermost planets of the solar system, make for excellent viewing throughout the end of September. Here's how to locate and view ...

The sun warms our planet every day, provides the light by which we see and is necessary for life on Earth. But what is it exactly, and what will happen when it burns itself out?

To track the Red Planet's spin rate, planetary scientists relied on the Rotation and Interior Structure Experiment (RISE) onboard NASA's InSight lander.

While we generally picture the sun and planets when thinking about our solar system, it also consists of comets, asteroids and hundreds of moons.

More than 15 years after the discovery of fast radio bursts (FRBs)—millisecond-long, deep-space cosmic explosions of electromagnetic radiation—astronomers worldwide have been combing the universe to uncover clues about how and why they form.

Using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), astronomers from the Purple Mountain Observatory (PMO) in Nanjing, China, have observed a pulsar known as RRAT J1913+1330. Results of the observational campaign, published June 5 on the arXiv pre-print server, indicate that it is an extremely variable pulsar with peculiar properties.

A large international team of astronomers has discovered that the dwarf planet Quaoar is circled by a second ring. In their study, accepted for publication in the journal Astronomy & Astrophysics, the group discovered the second ring while they were studying the first known ring.

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new massive brown dwarf. The newfound object is nearly 80 times more massive than Jupiter and orbits an M-dwarf star known as TOI-5375. The finding was presented in a paper published April 10 on the arXiv pre-print server.

With data from the Kepler (NASA), Gaia (ESA) and SOHO (NASA/ESA) satellites, a team, led by Instituto de Astrofísica e Ciências do Espaço (IA) researcher Ângela Santos, seems to have put an end to the idea that the sun might not be a regular "sun-like" star. The results were published today (April 6) in Astronomy & Astrophysics.
