Anticrepuscular rays are essentially parallel , but appear to converge toward the antisolar point , the vanishing point , due to a visual illusion from linear perspective .

Astronomers are anticipating the appearance of a “new star” triggered by an explosive event that could appear in the night sky anytime between now and September. ‘Once-in-a-lifetime ...
