Northern Lights Visible Across Multiple US States Tonight

Aurora displays are expected to be visible as far south as Idaho and New York tonight and early tomorrow morning due to a large hole that has opened in the sun's coronaSource 1. Moderate geomagnetic storm conditions are anticipated from 5 p.m. EDT Friday until roughly 2 a.m. EDT Saturday, which could trigger strong auroras and minor to moderate radio blackoutsSource 1.

Rare Four-Planet Parade Visible in Pre-Dawn Sky

Mercury, Mars, Saturn, and Neptune are appearing in a rare compact grouping in the eastern sky before sunrise between April 16-23, with peak visibility on April 18-20Source 2. Northern Hemisphere observers have roughly 30 minutes before sunrise to view the planets, though most casual observers will realistically see two to three planets due to the low angle and light pollutionSource 2.

Artemis II Astronauts Complete Historic Moon Mission

NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen successfully splashed down in the Pacific Ocean on April 10, 2026, concluding their 10-day Artemis II missionSource 3. The crew surpassed the Apollo 13 record for farthest crewed spaceflight and captured unprecedented views of the far side of the MoonSource 3.

AI Reveals Microbiome Links to Early-Onset Colorectal Cancer

City of Hope researchers are presenting findings at the AACR 2026 Annual Meeting showing that the gut microbiome differs between early- and late-onset colorectal cancer among at-risk populationsSource 5. This research may help explain why colorectal cancer has been rising in younger adultsSource 5.

New Pathway Identified for Colorectal Cancer Immunotherapy Resistance

City of Hope scientists have identified a newly discovered pathway that explains why many colorectal tumors resist immunotherapy, a finding being presented at AACR 2026Source 5. This breakthrough could lead to improved treatment strategies for patients with treatment-resistant colorectal cancerSource 5.
