Comet Nishimura (2023 P1) by Michael Jaeger Sept. 5, 2023 — Comet Nishimura on the morning of September 5th, on its way in. The comet is the green bit at left. The star cluster at upper right is the Beehive. The brilliant light at lower right is Venus. Right-click image to open higher-res version in new tab. Michael Jäger took this view "from my observatory in Martinsberg, Lower Austria." It's a stack of eight 30-second exposures he made using a DSLR camera with a 50-mm lens at f/2.5.

Comet Nishimura swings by for binoculars and telescopes. Comet Nishimura (2023 P1), discovered just last month, is brightening toward its September 17th perihelion.

The comet starts this week very low in the dawn sky. You'll need a low view to the east-northeast on the mornings of September 9th, 10th, and maybe 11th. The farther north you live the better. The waning crescent Moon won't pose interference.

By the 13th or 14th the comet shifts to the low evening sky, just above the west-northwest horizon during early to mid-twilight. Day by day it will move leftward, but no higher, to stand barely over the west horizon on its perihelion date, the 17th. This is also its predicted date of peak brightness — possibly 2nd magnitude, not counting the ill effects of bright twilight and atmospheric extinction that low.

Given those factors, will it ever be even slightly visible to the naked eye? Time will tell. So will very clear air. See Bob King's New Comet Nishimura for more info and finder charts. More news is also in his update.

Big freeze drove early humans out of Europe

From BBC News, By Pallab Ghosh- Science correspondent, Edited by - Amal Udawatta, IMAGE SOURCE, PHILIPPE PSAILA/SCIENCE PHOTO LIBRARY Image caption, Remains of a primitive human species known as Homo erectus have been found in Europe dating back to 1.4 million years ago. A big freeze previously unknown to science drove early humans from Europe for 200,000 years, but they adapted and returned, new research shows. Ocean sediments from 1.1 million years ago show temperatures suddenly dropped more than 5C, scientists say. They say our early ancestors couldn't have survived as they didn't have heating or warm clothes. Until now, the consensus had been that humans had existed in Europe continuously for 1.5 million years. Ancient humans' stone tools found in Kenya Ancient human remains found in County Armagh Ancient humans survived longer than we thought Evidence for the big freeze is found in sediments in the seabed off the coast of Lisbon, Portugal. Layers are deposited eac

INDIA’S CHANDRAYAAN 3 LANDS ON THE MOON; RUSSIA'S LUNA 25 CRASHES

From - Sky & Telescope By - David Dikinson, Edited by - Amal Udawatta, The first surface image received from Chandrayaan 3. ISRO In a first for the nation, India’s Chandrayaan 3 soft-landed in the lunar south pole region of the Moon. Russia’s Luna 25 lander crashed, however. Today was a “historic day for India’s space sector,” says India’s prime minister, Narendra Modi, on X , formerly known as Twitter. "Congratulations to ISRO for the remarkable success of Chandrayaan 3 lunar mission.” The landing occurred near Manzinus U Crater on the lunar nearside at 12:34 Universal Time (UT) (8:34 a.m. Eastern Daylight Time, or EDT) on Wednesday, August 23rd. This makes India the fourth nation to soft-land on the Moon, after the United States, the former Soviet Union, and China. ESA’s European Space Tracking system (ESTRACK) and NASA’s Deep Space Network (DSN) partnered with ISRO to provide global tracking coverage for Chandrayaan 3. A cheering mission contr
