TEHRAN (ANA)- Astronomers using data from NASA's Hubble Space Telescope and other observatories have uncovered a link between Neptune's disappearing clouds and the Sun's 11-year solar cycle.

TEHRAN (ANA)- An international team of astronomers led by the Weizmann Institute of Science (WIS) has discovered a hot Jupiter with an extreme temperature difference between its two sides.

TEHRAN (ANA)- Planetary scientists at the ETH Zurich now know how thick the Martian crust is, thanks to the strongest Marsquake ever observed.

TEHRAN (ANA)- A polar cyclone has been spotted at the Uranus’ north pole, researchers at the Jet Propulsion Laboratory in Pasadena, California, reported.

TEHRAN (ANA)- Star cluster M92, a densely packed ball of stars roughly 27,000 light-years from Earth, is about 13.8 billion years old, scientists at the University of Texas found.

TEHRAN (ANA)- NASA's Hubble Space Telescope has spotted a galaxy about 50 million light-years away that holds some surprises, the agency said.

TEHRAN (ANA)- Scientists at the University of California used an unprecedented technique to detect that levels of helium are rising in the atmosphere, resolving an issue that has lingered among atmospheric chemists for decades.

TEHRAN (ANA)- The rings that make Saturn such a spectacle are probably heating its atmosphere and making it glow at ultraviolet wavelengths, Harvard University researchers found.

TEHRAN (ANA)- The number of known mountains in Earth’s oceans has roughly doubled and global satellite observations have revealed nearly 20,000 previously unknown seamounts, scientists at the University of California said.

TEHRAN (ANA)- Using first-of-their-kind observations from the James Webb Space Telescope, a University of Minnesota Twin Cities-led team looked more than 13 billion years into the past to discover a unique, minuscule galaxy that generated new stars at an extremely high rate for its size.
