Certain lichen species can withstand Mars-like conditions with an X-ray radiation dose of 50 Gy (Grays) that is expected on the Mars surface over one year of strong solar activity, according to new ...

Molecular signaling pathways are communication systems that transmit messages within and between cells. According to a new study by University of Geneva scientists, inhibiting one such system, called ...

Light from an extremely distant spiral galaxy was bent and magnified by the gravity of a member of the galaxy cluster SMACSJ0028.2-7537 into a ring-like structure, called an Einstein ring. Einstein ...

“Nobody had really considered the possibility of convection in the crust of Venus before,” said Washington University in St. Louis Professor Slava Solomatov. “Our calculations suggest that convection ...

A new study by University of California, San Diego computational astrophysicist Ethan Nadler shows that star formation can occur in halos down to 10 million solar masses through molecular hydrogen ...

2MASX J23453268-0449256 (J2345-0449 for short), an extremely massive, rapidly rotating, jet-launching spiral galaxy approximately 947 million light-years in the constellation of Aquarius, harbors a ...

Emissions from the upper-atmospheric trihydrogen cation (H 3+) have been used to study the global-scale interactions of Jupiter, Saturn and Uranus with their surrounding space environments for over 30 ...

Paleontologists in China have unearthed a relatively complete skull and vertebrae that belonged to a previously unknown metriacanthosaurid theropod dinosaur from the Middle Jurassic period.

Apes and monkeys possess special anatomical structures in their throats called vocal membranes, which disappeared from humans through evolution to allow for more stable speech. However, the exact ...

“Planetary nebulae are the spectacular final display at the end of a giant star’s life,” Hubble astronomers said in a statement. “Once a red giant star has exhausted its available fuel and shed its ...

Astronomers using the MUSE instrument at ESO’s Very Large Telescope (VLT) have detected supermassive black hole-driven winds in the barred spiral galaxy NGC 4945. NGC 4945 resides over 12 million ...
