Today is 2019's first Friday the 13th

Exactly 13 weeks after today, 2019's second Friday the 13th will fall in December. Zoinks! By the way, an irrational fear of Friday the 13th is called friggatriskaidekaphobia. Read more.

Astronomers spy a 2nd interstellar visitor

Astronomers are buzzing this week about a newly discovered object that appears to have come from interstellar space. The official confirmation that this object - labled C/2019 Q4 - is interstellar has not yet been made, but, if it is, it's only the second such object detected. How exciting is that? First, there was only one known object - which earthly astronomers named 'Oumuamua - observed and confirmed as interstellar, in October 2017. And now there are two. Read more.

Memorial lights over New York City

Taken by Gabriel Rivas at 7th Avenue South & Grove Street, New York, New York. He wrote: "You can just make out a planet (Saturn?) through the World Trade Center memorial lights. 9/11/19, 7:49 p.m." The soaring beams of light over Lower Manhattan are a beautiful tribute to those who died 18 years ago. A recent study, though, shows these lights are tough on migrating birds.

Yesterday evening's Venus-Mercury conjunction

View at EarthSky Community Photos. | Venus and Mercury conjunction - just 8 degrees from the sunset - captured by Helio C. Vital in Rio. Venus is the brighter object above and to the right of the tall pole. Mercury is the fainter object, left of the pole, about midway up. Neither of these planets is visible to the eye alone now because they are so close to the sunset. But Venus is bright. Helio managed to capture it a few days ago. And Venus doubtless helped him find fainter Mercury, too, yesterday evening. Thank you, Helio! By the way, when will you see Venus and Mercury in the evening sky, using just your eye? Likely not until late September or October. Click for EarthSky's September planet guide.
