Japanese astronomers have performed long-term multiwavelength observations of a supernova remnant (SNR) designated SNR G298.6−0.0. They found that G298.6−0.0 is an old SNR interacting with molecular clouds. The new findings ...
How are galaxies born, and what holds them together? Astronomers assume that dark matter plays an essential role. However, as yet it has not been possible to prove directly that dark matter exists. A research team including ...
