The Sun rises exactly in east traveling through sky for 12 hours, sets exactly in west; every place on Earth experiences a ~12-hour day, 18:19 UTC (08:19 HST).
Appearing when Earth passes through the tail of Comet 21P / Giacobini-Zinner, the comet was a perihelion in 2025; speculation has arisen this may be a year with peak yielding many hundreds per hour. However, the Full Moon the day prior may compromise viewing. Most years show 10-20 per hour, […]
One of 2 showers yearly from Halley’s Comet dust, one dust cloud from Halley's path toward the Sun, and one from its path away. Orionids appear to radiate from Constellation Orion, are swift (~67 km/sec), and can be bright and leave persistent trains. Between 10 and 75 meteors per hour […]
Known for fireballs in a swarm year such as 2025, they will have to compete with a Full Moon Nov 5. Appearing in the Constellation Taurus, they emanate from Comet Encke (2P). Traveling relatively slowly, ~27km / second, there may be 5-7 per hour. Southern Taurids are active Sep 20 […]
Online auction to raise scholarship funds, of items such as NASA Astronaut mementos. 99% / 4-star rating from Charity Navigator for Astronaut Scholarship Foundation.
From Comet Encke dust cloud, with peak rate 5 per hour. Moon is 53% full.
From Comet Tempel-Tuttle (55P) dust cloud, peak rate 15 per hour. Moon is 9% full.
The northern hemisphere's autumn equinox on Mars marks the beginning of the autumn season in the northern hemisphere and coincides with the start of the planet's dust storm season. Unlike Earth, which has a nearly circular orbit, Mars' elliptical orbit causes its seasons to vary in length.
Appearing at brightest magnitude 0.9, traveling from SW to E, Hubble Space Telescope will appear over Hawaiian Islands from 18:56:02 to 19:03:04 HST.
Usually strongest meteor shower yearly, up to 150 hourly. Moon is 30% full.
Occurs 05:01 HST, 15:01 UTC; It is the winter solstice in the Northern Hemisphere, resulting in the shortest day and longest night of the year; and conversely, it is the summer solstice in the Southern Hemisphere, bringing the longest day and shortest night.
From Comet Tuttle (8P), with up to 10 per hour. Moon only 3% full helps viewing on peak nights; active Dec 17-26.
At magnitude 2.9, the Hubble Space Telescope will travel over Hawaiian Islands from SSE to E, rising at 04:58:50 to 05:04:49 HST.
NASA Juno indicates Europa ice may be 6x deeper than thickest Antarctic ice; timing of craft planned plunge into Jupiter clouds TBD | ESA JUICE heading toward Earth gravity assist Sep 2026.
The Quadrantid shower is known for its brief, intense peak, lasting only a few hours. Appearing to radiate from Constellation Quadrans Muralis, there can be 25-120 meteors per hour. Comets are traveling ~40km/second and come from the debris trail of Asteroid 2003 EH1, discovered in 2003 by the Lowell Observatory […]
08:00 HST, 18:00 UTC; Earth perihelion is the point in its orbit when it is closest to the Sun, occurring annually in early January.
Visible at -3.9 magnitude, the International Space Station will travel over Hawaiian Islands from NW to SE, rising at 04:48:07 to 04:54:02 HST.
Beginning 06:20:51 HST from the SSW, Tiangong will make a visible pass at brightest magnitude 1.2 over Hawaiian Islands, setting 06:29:49 in the ENE.
Total solar eclipse, starts 17:02:06 UTC (07:02:0 HST), will sweep across the Arctic, Greenland, Iceland, and northern Spain, offering up to 2 minutes of totality; Maximum Eclipse: 17:45:53
Best-known for occasional rare, intense bursts and bright, long-lasting fireballs, they average 3–6 meteors per hour, up to 25+; body producing them is still unknown; seen in the constellation Centaurus, making them most-visible in the Southern Hemisphere with viewing also from Hawai'i and southern Florida / Texas / Asia.
Begins 11:42 UTC (01:42 HST), maximum at 12:13 UTC, creating a "ring of fire" visible primarily over remote parts of Antarctica and the southern ocean; 96% of the sun obscured.
Mercury, Venus, Jupiter, Saturn, Uranus and Neptune form an arc across the sky, most visible in the west 20-40 minutes after sunset. Venus and Jupiter will be easily visible. Saturn and Mercury may be visible, but they will be lower on the horizon and set quickly. Uranus and Neptune will […]
Maximum eclipse 11:33 UTC (01:33 HST); visible across North America, the Pacific, East Asia, and Australia. The total phase (totality) lasts from 11:04 to 12:02 UTC.
Occurs 04:45 HST / 14:45 UTC; March equinox is known as the vernal equinox (or spring equinox) in the Northern Hemisphere and as the autumnal equinox (or fall equinox) in the Southern Hemisphere; it is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere […]
02:12 UTC (14:12 HT)
Predicted date for the comet to make a close pass by the Sun (perihelion), potentially triggering a sudden brightening and dramatic tail. If it survives the encounter, it may become visible to the naked eye. This event is part of a rare opportunity in April to potentially view two comets—C/2026 […]
Best seen from Northern Hemisphere, with a lower hourly rate in the Southern Hemisphere, Lyrids seem to stream from the Constellation Lyra. They actually derive from the debris trail of Comet C/1861 G1 Thatcher, which has a period of 415 years. Can be "fireball" bright but usually lack persistent trains, […]
17:24 UTC (07:24 HST).
Strongest viewed from southern tropics; north of the equator, expect medium rates of 10-30 per hour just before dawn, with this year's waning gibbous Moon reducing viewing to less than 10. Originating from Halley's Comet, seen in constellation Aquarius from April 19 to May 28, 2026.
22:46 HST on May 30 | 08:46 UTC on May 31.
Seen in the sunrise direction in the dark hour before dawn, with a predicted rate of 60 to 200 per hour, 2026 will have a thick waxing crescent Moon so watch from a place in the Moon shadow or with a distant object that blocks moonlight. Called the most-active daytime […]
