Normally, it would be much too faint to view, even with the world’s largest telescopes.

They also used Icarus to test a theory of dark matter, and to probe the makeup of a foreground galaxy cluster.

The new virus is named swine acute diarrhea syndrome coronavirus (SADS-CoV). It does not appear to infect people, unlike SARS-CoV which infected more than 8,000 people and killed 774.
