2021: August 1 – 6: Morning Moon, Bright Stars

August 1 – 6, 2021:  The morning moon wanes toward its New moon phase in the eastern sky.  It passes the bright stars that are prominent in the evening sky during the winter season in the northern hemisphere.  The stars have been making their first appearances in the morning sky during summer.  At this hour, Procyon and bright Sirius are the last stellar duo to appear.

2021, May 29: Evening Star Venus, Mercury, Mars

May 29, 2021: Three planets are in the evening sky.  Brilliant Venus is low in the west-northwest after sunset.  Speedy Mercury is leaving the sky after its best evening performance of the year.  It is below Venus.  Mars is higher in the western sky, in Gemini to the lower left of Pollux.

2021, May 28: Close Venus – Mercury Conjunction

May 28, 2021:  This evening Mercury passes brilliant Venus for the second of three conjunctions during this evening apparition of the second planet from the sun.  Use a binocular about 45 minutes after sunset to see the speedy planet 0.4° to the lower left of Venus.  This is the closest visible conjunction until 2033.

2021, May: Year’s Best Mercury Evening Appearance

Mercury’s best evening appearance of 2021 occurs during May.  The planet is visible in the west-northwest above Venus after sundown.  The appearance begins during late April. On May 28, the apparition ends with a close Venus – Mercury conjunction, the closest easily visible until 2033. About 30 Venus – Mercury conjunctions occur during the interval, but some close groupings are lost in the sun’s glare.
