Astronomers May Have Spotted the Birth of a Planet

Javier Barbuzano, Science Writer by Javier Barbuzano 29 August 202329 August 2023

Lumps of dust are spiraling around a young star 5,000 light-years away. They could be Jupiter-like planets in the making.

An image of a dark brown sphere and its rings is backlit against a black background. The closer rings glow in yellow-orange and are haloed by the dusty ring system in blue-white. Several bright specks are visible.

Saturn’s Shiny Rings May Be Pretty Young

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 9 June 20239 June 2023

The rings are fairly shiny despite being bombarded by dust, indicating that they haven’t been around for very long.

In this composite image of the Tarantula Nebula, the blue and purple patches represent X-ray data from the Chandra X-ray Observatory, and the red and orange gas clouds, which look like roiling fire, represent infrared data from the James Webb Space Telescope.

Deluges of Data Are Changing Astronomical Science

Katherine Kornei, Science Writer by Katherine Kornei 27 March 202329 March 2023

Astronomers today are more likely than ever to access data from an archive rather than travel to a telescope—a shift that’s democratizing science.

El papel central de la agricultura en el calendario de horizonte azteca

by Humberto Basilio 8 March 20238 March 2023

Los calendarios de horizonte fueron clave para medir el tiempo para las culturas pre-hispánicas de la cuenca del Valle de México. Un nuevo estudio sugiere que los calendarios se usaron para gestionar los ciclos agrícolas.

Marauding Moons Spell Disaster for Some Planets

Katherine Kornei, Science Writer by Katherine Kornei 6 March 20236 March 2023

In solar systems beyond our own, some moons might eventually collide with their host planets, new simulations suggest.

Quaoar’s Ring Defies Gravity

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 3 March 202324 May 2023

The dwarf planet’s ring makes astronomers question whether a long-held theory about ring and moon formation needs tweaking.

A large, dark cloud is contained within the frame. In its top half it is textured like smoke and has wispy gaps, whereas at the bottom and on the sides it fades gradually out of view. On the left are several orange stars: three each with six large spikes and one behind the cloud, which colors it pale blue and orange. Many tiny stars are visible, and the background is black.

Complex Organic Ices Discovered in a Star-Forming Cloud

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 24 February 20231 March 2023

The presence of complex organic molecules such as methanol, ethanol, and acetaldehyde in a molecular cloud suggests that these and simpler ices might be available to planetary systems right from the start.

Starry Nights Are Disappearing

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 10 February 2023

Stars dim as the sky gets brighter, a result of expanding cities and bright LEDs. Simple low-tech changes can help preserve dark night skies.

Agriculture at the Center of the Aztec Horizon Calendar

by Humberto Basilio 8 February 202315 March 2023

Horizon calendars were a key part of time measurement for pre-Hispanic cultures in the Basin of Mexico. A new study suggests that calendars were used to manage the agricultural cycle.

A New Journey Around (and Around) the Sun

by Daniele Telloni, Francesco Valentini and Raffaele Marino 25 February 202231 January 2023

The Solar Orbiter just completed its commissioning phase while en route to the Sun. It has already provided valuable looks at solar campfires and Venus’s magnetic fields, and it promises much more.
