Image: Patchy water clouds and chemical changes observed on brown dwarf WISE 0855

WISE 0855 represents the coldest known brown dwarf, an object too large to be a planet but too small to sustain the nuclear fusion that powers stars. With a temperature of roughly 265 Kelvin, it is cold enough to host complex atmospheric phenomena similar to those seen on gas giant planets in our solar system. Observations reveal that this object is not uniform but features patchy water clouds distributed throughout its atmosphere, which influence its light patterns over time. To study this, ...

Image: Silicate clouds and gaseous silicon monoxide identified in three early L-dwarf objects

Analysis of three early L-dwarfs, HD 89744 B, Gliese 1048 B, and LSPM J0632+5053 B, reveals gaseous silicon monoxide and silicate clouds in their atmospheres. JWST data confirms these mineral clouds form as silicon gas condenses, mimicking processes in giant planets....

Frequently Asked Questions about nearby stars

What is the nearest star?

Nearest star is Proxima Centauri, located approximately 4.24 light-years (1.30 parsecs) from the Sun. It is part of the Alpha Centauri star system, which also includes Alpha Centauri A and Alpha Centauri B.

What are the nearest stars to Earth?

Nearest stars to Earth include the Alpha Centauri system (Alpha Centauri A, Alpha Centauri B, and Proxima Centauri), Barnard's Star, and Wolf 359. There are also brown dwarfs Luhman 16 and WISE 0855−0714.

What is the solar neighborhood?

Solar neighborhood (also Local Interstellar Cloud) is the region of interstellar space that surrounds the Sun with diameter about 15 light years. Stellar Catalog database includes all stars contained within this region.

How do astronomers measure distances to stars?

Astronomers use methods like parallax, standard candles, and redshift to measure distances to stars. Parallax is especially useful for nearby stars in our solar neighborhood, while other techniques help map the universe beyond.

Are there any exoplanets orbiting the nearest stars?

Yes, several exoplanets have been discovered orbiting the nearest stars. For example, Proxima Centauri has an exoplanet called Proxima Centauri b, which is located in the star's habitable zone and is the closest known exoplanet to Earth.

Why are the nearest stars important for astronomy and physics?

The nearest stars provide valuable laboratories for studying stellar evolution, space environments, and the fundamental physics of stars. Observing these stars helps astronomers understand the structure of our galaxy and the broader universe.

StellarGuide: Звезды

Звезды

Звёзды — это огромные шары раскалённого газа, которые светятся благодаря выработке энергии в процессе ядерного синтеза в их ядрах. Большинство звёзд состоит в основном из водорода и гелия. В центре звезды из-за высокого давления и температуры атомы водорода сливаются в гелий, высвобождая огромное количество энергии в виде света и тепла.
