Milky Way Urban Style

In a cosmic vista you can never see, the Milky Way arcs through the night above Seoul, South Korea. Remarkably, this urban night skyscape reveals our galaxy's faintly luminous central region and dark obscuring dust clouds in spite of the brilliant city lights. To overcome the extreme light pollution of the metropolitan area and record faint cosmic details, an infrared filter was used to capture the night scene in a single exposure. While the filter transmits predominately infrared light, it still passes some visible light to give the scene a natural appearance. The view is from Seoul's Ttukseom Hangang Park, with the Han River and a well lit railway bridge across the foreground. The 123 story Lotte World Tower looms in the distance, the tallest building in South Korea.

A Look At Eight Outbursts Of Comet 7P/Pons-Winnecke

June 26, 2026

Cometary outbursts may be used as a means to infer the physical processes occurring on cometary nuclei. To that end, we studied eight outbursts of comet 7P/Pons-Winnecke identified between 2021 June 3 and 2021 August 31.

The data analyzed consisted of optical images and derived photometry of the comet from the Las Cumbres Observatory network of telescopes.

The outburst strengths relative to the ambient coma ranged from -0.2 to -1.1 mag, and the ejecta themselves had apparent brightnesses ranging from 17.4 to 13.3 mag.

The morphologies of the ejecta varied, suggesting that the events may have originated from different sources across the nucleus.

An order of magnitude estimation of the ejecta masses ranged from 105 – 106 kg, similar to other mini-outbursts of comets.

The surface-area normalized outburst rate estimated during this time period is similar to comets 41P/Tuttle-Giacobini-Kresák, 9P/Tempel 1 and 46P/Wirtanen, but 10 times larger than that observed at comet 49P/Arend-Rigaux.

However, a comparison to the mini-outburst rate of comet 67P/Churyumov-Gerasimenko reveals significant discrepancies between Rosetta spacecraft results and those from ground-based telescopes.

We also investigate whether or not cometary outbursts from 7P in the 19th century are needed to explain outbursts in meteor shower rates observed in the 20th century.
