TEHRAN (ANA)- Researchers are using black hole shadows to challenge Einstein’s theory of relativity, a report said, adding, with new simulations and future ultra-sharp telescope images, they may uncover signs that his famous equations don’t tell the whole story.

TEHRAN (ANA)- The early growth of the gas giant carved rings that formed primitive meteorites and shaped the architecture of the inner solar system.

TEHRAN (ANA)- A team of Indian researchers has discovered that baker’s yeast can survive extreme Martian-like conditions involving high-intensity shock waves and toxic perchlorate salts.

TEHRAN (ANA)- A massive crater hidden beneath the Atlantic seafloor has been confirmed as the result of an asteroid strike from 66 million years ago.

TEHRAN (ANA)- Iranian researchers at the University of Science and Technology, in collaboration with the Faculty of Physics, succeeded in simulating lunar soil based on the compositions of the Apollo 14 mission sample.

TEHRAN (ANA)- New research suggests that planets outside our solar system contain far less surface water than scientists once believed.

TEHRAN (ANA)- A recent study led by Dr. Michael Starkey of the Southwest Research Institute has delivered the first observational evidence from the Magnetospheric Multiscale (MMS) Mission of pickup ions (PUIs) and their related wave activity in the solar wind near Earth.

TEHRAN (ANA)- NASA’s Perseverance rover has uncovered strange chemical and mineral patterns in Jezero Crater’s Bright Angel formation that may be the strongest hints yet of ancient Martian life.

TEHRAN (ANA)- Scientists are unraveling the mysteries of "steam worlds"—exoplanets known as sub-Neptunes that are rich in water but orbit so close to their stars that their surfaces are shrouded in thick atmospheres of vapor.

TEHRAN (ANA)- Mars’ glaciers are over 80% pure ice, formed by similar processes worldwide. This discovery sheds light on past climate and future exploration resources.
