A research team from the Northwestern University discovered that a stellar stream in the Milky Way galaxy- to which belongs our planet- houses a large cluster of stars that were born at the same time and travel in the same direction.
While researchers have long known that stars form in groups, most known clusters are spherical in shape. Only recently have astrophysicists started to find new patterns in the sky. They believe long strings of stars were once tight clusters, gradually ripped apart and stretched by tidal forces.

Images of two iconic planetary nebulae taken by the Hubble Space Telescope are revealing new information about how they develop their dramatic features. Researchers from Rochester Institute of Technology and Green Bank Observatory presented new findings about the Butterfly Nebula (NGC 6302) and the Jewel Bug Nebula (NGC 7027) at the 237th meeting of the American Astronomical Society on Friday, Jan. 15.
Hubble s Wide Field Camera 3 observed the nebulae in 2019 and early 2020 using its full, panchromatic capabilities, and the astronomers involved in the project have been using emission line images from near-ultraviolet to near-infrared light to learn more about their properties. The studies were first-of-their-kind panchromatic imaging surveys desig
Extragalactic Old Faithful : Scientists Discover Galaxy That Erupts Regularly
KEY POINTS
The galaxy s next outbursts are expected to happen in April and August
It s possible that the events are caused by a tidal disruption event
A team of researchers discovered a galaxy with a rather odd behavior: it emits flares at regular intervals. What could be causing the galaxy s flares?
Galaxies that have unusually active centers are classified by astronomers as active galaxies. NASA says these centers can even produce more energy than all of the stars in the host galaxy combined.
In November of 2014, the All-Sky Automated Survey for Supernovae (ASAS-SN) spotted an outburst event, called ASASSN-14ko, in active galaxy ESO 253-3, which is 570 million light-years away from the Earth. At the time, scientists thought it was a supernova explosion, a one-time outburst.
