Astronomers using the GBT have discovered the most massive neutron star to date, a rapidly spinning pulsar approximately 4,600 light-years from Earth. This record-breaking object is teetering on the edge of existence, approaching the theoretical maximum mass possible for a neutron star.

An international team of astronomers has discovered one of the largest features ever observed in the center of the Milky Way – a pair of enormous radio-emitting bubbles that tower hundreds of light-years above and below the central region of our galaxy.

New radio wave images made with the Atacama Large Millimeter/submillimeter Array (ALMA) provide a unique view of Jupiter’s atmosphere down to fifty kilometers below the planet’s visible cloud deck.

New ALMA observations provide an unprecedented close-up view of a swirling disk of cold interstellar gas rotating around a supermassive black hole.

ALMA has made the first-ever observations of a circumplanetary disk.

Radio telescope observations have made it possible for astronomers to use mergers of neutron-star pairs as a valuable new tool for measuring the Universe’s expansion.
