Washington : Scientists have confirmed that some of the X-ray emissions in universe originate from a huge bubble of hot ionised gas enveloping our solar system, a finding that strengthens our understanding of the solar neighbourhood’s early history, says PTI.
They also detected an entire group of X-rays that do not come from any known source – unveiling a new cosmic mystery. In the last century, humans realised that space is filled with types of light we cannot see – from infrared signals released by hot stars and galaxies, to the cosmic microwave background that comes from every corner of the universe.
Some of this invisible light that fills space takes the form of X-rays, the source of which has been debated over the past few decades. Researchers from University of Miami in the US confirmed some of our ideas about where these X-rays come from, using data from the DXL (Diffuse X-ray emission from the Local galaxy) sounding rocket, which was launched in 2012.
