Scientists are still hunting for the source of the faint, persistent hum of gravitational waves discovered reverberating through the Milky Way last year. Those waves could point to more than one tantalizing source, new research suggests. The discovery team, the North American Nanohertz Observatory for Gravitational Waves, or NANOGrav, collaboration, strongly suspects the ripples in […]

That’s a little how our team of astronomers felt when we discovered a massive planet, more than 13 times heavier than Earth, around a […]
A newfound population of stars in nearby dwarf galaxies represents the long-sought progenitors of a specific type of stellar death, or supernova, according to new research. Theories have shown that, for every three massive stars, one is stripped of its outer hydrogen layers across hundreds, or even thousands, of years such that its scorching hot […]
