The future lifespan of plants just got extended

For now, the future of life on Earth is in human hands. But after the anthropocentric era, the situation starts to get dicey. The sun’s luminosity is increasing over time, about 1% every 110 million years, so the Earth’s surface will gradually get warmer (but at a vastly slower rate than today’s global warming).

New method traces molecular gas mass in distant galaxies

Prof. Zhao Yinghe from the Yunnan Observatories of the Chinese Academy of Sciences, along with collaborators, have conducted a study examining the correlation between the [C II] 158 micron emission and the CO(1-0) line. Their findings were published in The Astrophysical Journal.

Observers investigate a nearby galaxy cluster merger

Using the Very Large Array (VLA), an international team of astronomers have observed a nearby galaxy merger known as CIZA J0107.7+5408. Results of the observational campaign, presented December 20 on the preprint server arXiv, could help us better understand the merging processes that take place between galaxy clusters.

Astronomers discover an ultra-massive grand-design spiral galaxy

Using the James Webb Space Telescope (JWST), an international team of astronomers has detected a new grand-design spiral galaxy as part of the PANORAMIC survey. The newfound galaxy, named Zhúlóng, is extremely massive and appears to be the most distant spiral galaxy identified so far. The finding was detailed in a paper published December 17 […]

Astronauts face unique visual challenges at lunar south pole

Humans are returning to the moon—this time, to stay. Because our presence will be more permanent, NASA has selected a location that maximizes line-of-sight communication with Earth, solar visibility, and access to water ice: the Lunar South Pole (LSP).

Researchers reveal changes in geometry and kinematics of the broad-line region in active galactic nuclei

Dr. Feng Haicheng from the Yunnan Observatories of the Chinese Academy of Sciences, along with his collaborators, has made progress in studying the geometrical and kinematical evolution of the broad-line region (BLR) in active galactic nuclei (AGN). The study was published in The Astrophysical Journal.

Two populations of dark comets in the solar system could tell researchers where the Earth got its oceans

The water that makes up the oceans acted as a key ingredient for the development of life on Earth. However, scientists still do not know where the water here on Earth came from in the first place.

In Disney’s ‘Moana,’ the characters navigate using the stars—an astronomer explains how these methods work

If you have visited an island like one of the Hawaiian Islands, Tahiti or Easter Island, also known as Rapa Nui, you may have noticed how small these land masses appear against the vast Pacific Ocean. If you’re on Hawaii, the nearest island to you is more than 1,000 miles (1,600 kilometers) away, and the […]
