For the first time, astronomers have detected a radio signal from the massive explosion of a dying white dwarf
Patience and persistence pays off in ways researchers never expected, allowing them to hear the dying whispers of a distant star.
Astronomers have directly detected a massive exoplanet. The method could transform the search for life beyond Earth.
There are many techniques to search for planets orbiting other stars. Perhaps the simplest of these is called direct imaging, but it's not easy.
