Sunday Night Doubleheader: Catch the 2025 Leonid Meteors and an Aurora Encore
November 16, 2025Keep an eye on the sky Sunday night and early Monday morning for the Leonid meteors, and a possible second auroral storm. Once every other generation, the Lion roars. If skies are clear Monday morning, keep an eye out for one of the best annual November showers, the Leonid meteors. Also as an extra treat, the skies may stream with aurora once again.

Miniature Binary Star System Hosts Three Earth-sized Exoplanets
November 14, 2025A new discovery adds to the growing menagerie of exoplanets. These days, word of a new exoplanet discovery raises nary an eyebrow. To date, the current number of known exoplanets beyond our solar system stands at confirmed 6,148 worlds and counting. But a recent study out of the University of Liège in Belgium titled Two Warm Earth-sized Planets and an Earth-sized Candidate in the Binary System TOI-2267 shows just how strange these worlds can be.

Spying Interstellar Comet 3I/ATLAS Near Perihelion
October 28, 2025Everyone’s favorite interstellar comet 3I/ATLAS isn’t really hiding near perihelion this week, as amateur astronomers reveal. Don’t believe the breathless ballyhoo that you’re currently reading around the web about interstellar Comet 3I/ATLAS. In a clockwork Universe, comets are the big wildcard, and interstellar comets doubly so. This particular comet is scientifically interesting enough in its own right, no alien interlopers needed.

XRISM Catches a Pulsar’s Cosmic Wind...and Sees a Surprising Result
October 24, 2025The Universe is a strange place. The X-Ray Imaging and Spectroscopy Mission (XRISM) orbiting observatory recently highlighted this fact, when it was turned on a pulsar to document its powerful cosmic winds. The discovery comes courtesy of ESA’s Resolve instrument, a soft X-ray spectrometer aboard XRISM. The study looked at neutron star GX 13+1. This is a strong X-ray source located in the constellation Sagittarius, very near the galactic plane towards the core of our galaxy. GX 13+1 is about 23,000 light-years distant.

ESA’s Swarm Constellation Sees Growth in the Magnetic Field’s 'Weak Spot'
October 17, 2025Earth is a dynamic place, both on its surface and down to its very core. The European Space Agency (ESA) recently released findings from its Swarm constellation of Earth-observing satellites highlighting this fact, documenting activity in the planet’s magnetic field during its decade plus of extended operations. One key finding shows the well-known Southern Atlantic Anomaly is expanding in size.

Arab Scholars May Have Noted the Supernovae of 1006 and 1181
October 14, 2025It’s great to see old astronomical observations come to light. Not only can these confirm or refute what’s known about historic astronomical events, but they can describe what early observers actually saw. A recent study cites two Arabic texts that may refer to accounts of two well-known supernovae seen in our galaxy: one in 1006 AD and another in 1181 AD.

Comet A6 Lemmon's Encore October Evening Show
October 07, 2025October 2025 may provide a memorable sky scene, as Comet C/2025 A6 Lemmon puts on an encore appearance at dusk. The comet joins Comet R2 SWAN, which slides 0.26 Astronomical Units (AU) past Earth on October 20th. Both are currently fine objects for binoculars or a small telescope, vying for top spot at magnitude +6.

Catching the October Action With Jupiter’s Moons
October 03, 2025Jupiter and its moons are busy in October. If skies are clear, be sure to set your alarm and follow the largest planet in our solar system this month. While massive Jupiter always warrants a view through even a small telescope, its four major Galilean moons warrant special interest, as we’re in the midst of a season of rare double shadow transits.

Dedicated Amateur Discovers Supernova in Remote Galaxy
October 01, 2025Astronomy is increasingly becoming an online affair. Recent discoveries of interstellar Comet 3I/ATLAS and R2 SWAN highlighted this fact, when both were first discussed on message boards and verified via remote telescopes before confirmation. Another recent find also shows what’s possible, as devoted amateur astronomer Filipp Romanov accomplished an amazing feat, and discovered a supernova in a remote galaxy.

Catch a Far-Flung Partial Solar Eclipse This Weekend
September 18, 2025Subtle astronomical events can still produce memorable scenes, hidden away in distant locales. Such a spectacle goes down on Sunday/Monday, September 21st/22nd, with a partial solar eclipse. Although the eclipse only skims the southernmost portion of the South Pacific, viewers along the eastern coast of Australia, Antarctica and all of New Zealand will see an unforgettable sight, as a partially-eclipsed Sun rises out of the sea.

Saturn 'On Razor's Edge' at Opposition for 2025
September 17, 2025It seems like most of the planets have fled the evening scene. But that’s about to change this week. Saturn reaches opposition on Sunday, September 21st, passing closest to the Earth at just over 8.5 Astronomical Units (AU) or 1.3 billion kilometers distant, and rising opposite to the setting Sun. This marks the best time to view the ringed world, as it dominates the night sky from sunset until sunrise.

New Bright Comet SWAN Could Perform a Surprise October Show
September 15, 2025A new comet approaching from sunward could make a fine dusk appearance in October. There was chatter on the boards this past Friday September 12th, about a comet seen in the Solar Wind Anisotropies (SWAN) images near the Sun. Tentatively named SWAN25B and now formally designated as C/2025 R2 SWAN, this comet could put on a brief show in late September into October if it holds up.
