One of the boldest dreams in modern astronomy is the search for Earth-like worlds beyond our solar system. These exoplanets may hold oceans, rocky ground, and even atmospheres rich in oxygen or ...

The article discusses three main telescope types: refractors (best for bright objects, portable), reflectors (best for faint objects, larger apertures), and catadioptrics (compromise between aperture ...

Indeed, the planetary nebula seen above, known as the Red Spider Nebula and imaged by the James Webb Space Telescope (JWST), ...

A joint Hubble and James Webb Space Telescope (JWST) project to learn more about the dusty disk around the bright star Vega ...

A distant gas giant the size of 10 Jupiters is now the first planet outside Earth's solar system to be mapped in three dimensions.

For the first time ever, the James Webb Space Telescope has discovered an exoplanet by directly imaging it. The newfound world has a mass roughly similar to Saturn and orbits inside the debris disk ...

"The formation of planetary systems is not exclusive to stars but might also work around lonely starless worlds." Our parochial view of planets orbiting a central star — so familiar because it is the ...

Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system. It’s an unprecedented ...

Uranus, the seventh planet in the solar system, located between Saturn and Neptune, has long been a mystery. But by analyzing observations made by NASA’s Hubble Space Telescope over a 20-year period, ...

New observations suggest that the dwarf planet Makemake is surrounded by faintly glowing methane gas. Scientists are unsure if the gas is contained within a wispy atmosphere or being ejected into ...
