Many protoplanetary disks in which new planets are formed are much smaller than thought. Using the Atacama Large Millimeter/submillimeter Array (ALMA) scientists of the Leiden Observatory (the ...

How many stars like the Sun are circled by planets? Today, astronomers think they may be quite rare. They base that assessment on the observations of a group of stars, called T Tauri stars, that ...

An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. Across our galaxy, astronomers routinely observe a ...

Widespread magnetism dating from our solar system’s earliest beginnings some 4.57 billion years ago likely played a major role in creating orbital order out of chaos. But until now, magnetism’s role ...

When it comes to explaining how planets are formed, the protoplanetary hypothesis is the most widely accepted explanation. In simple terms, the donut-shaped disc of dust and gas around a star forms ...

The Hubble Space Telescope has captured a spectacular new image of the largest and most unusual protoplanetary disk ever observed around a single star. The object, officially known as IRAS 23077+6707 ...

ALMA, located in the Chilean Atacama desert, is the most powerful telescope for observing the cool Universe — molecular gas and dust. ALMA studies the building blocks of stars, planetary systems, ...

New research has confirmed that the celestial object may be the biggest of its kind ever found Riley Black - Science Correspondent The planet-forming disk is made of gas and dust. Radio: SAO/ASIAA/SMA ...
