Catch a Cycle of Lunar Occultations of Antares Starting This Week

Most of North America gets to see the Moon blot out Antares Thursday night.

The long drought of lunar bright star occultations ends this week, as the Moon meets the bright star Antares. This event is one of the best bright star versus the Moon occultations for 2023, and is a harbinger for a series of new occultations of the star once every pass, as the Moon swings through Scorpius the Scorpion every lunar synodic period or 29.5 days.

Comet P1 Nishimura Could Be Bright Over the Next Few Weeks

New Comet P1 Nishimura graces the August dawn sky…but how bright will it get?

Hello. In a predictable clockwork Universe, a new comet is always the one wildcard that can over- or under-perform expectations. The most dramatic ones often crop up with scant warning: witness Comet IRAS-Araki-Alcock in 1983, and Comet B2 Hyakutake in 1996.

Why 2023 is a Great Year for the Perseid Meteors

Don’t miss one of the best meteor displays of 2023, as the Perseids peak this coming weekend.

Grab a lawn chair, bring a friend, a red light and lots of bug spray: the August Perseids are active this week going into the weekend. You won’t want to miss ‘em if skies are clear, as 2023 is a banner year for the Perseids, one of the sure-fire performers when it comes to meteor showers.

A Fine Southern Apparition for Comet T4 Lemmon

The time to catch Comet T4 Lemmon is now, before it vanishes for another 36,000 years.

Often, icy interlopers creep up on the inner solar system, only to once again vanish into the abyss. Such is the case with long-period comet C/2021 T4 Lemmon, headed towards perihelion early next week.

Follow Comet E1 Atlas Through the July Sky

Comet C/2023 E1 ATLAS skirts the northern pole for summer northern hemisphere observers.

When it comes to comets, even the best predictions may often betray reality. Bright comets may fizzle as they approach the Sun, and fainter comets that ordinarily wouldn’t warrant a second look many suddenly flare into view.

Thankfully, the former seems to be the case with comet C/2023 E1 ATLAS, which has been over-performing expectations as of late, and recently brightened up into the range of binocular visibility at magnitude +10.

Startup PLD Space to Launch Europe’s First Reusable Rocket

PLD Space could launch its suborbital Miura-1 rocket this month.

Update: Game on… PLD Space has announced that they will attempt to launch Miura-1 tonight. The live webcast starts on June 17th (Saturday local time) at 1:00 AM Central European Time (11:00 PM Friday night on June 16th Universal Time, and 7:00 PM Eastern Daylight Saving Time), and the eight hour launch window begins at 2:00 AM CET/00:00UT/8:00 PM EDT.

A small space startup with big ambitions may be joining the private spaceflight club soon. This summer, Elche Spain-based PLD Space is set to carry out the first test launch of their single stage, suborbital Miura-1 rocket.

North Korea May Launch Spy Satellite Soon

Enigmatic North Korea may attempt to put a satellite in orbit, as early as this week.

Update: May 31stAlas, it was not meant to be. While North Korea’s latest satellite launched last night on the first day of the launch window at 21:29 Universal Time (UT), the rocket seems to have experienced an anomaly on the second stage, and the now posthumously named ‘Cheollima-1’ rocket with the ‘Malligyong-1’ (‘grand view’ (?) in Korean) satellite splashed down in the Sea of Korea. This trajectory would seem to indicate that the mission was indeed aiming for a sun-synchronous orbit.

Satellite spotters worldwide may have a new clandestine target to hunt for in orbit soon. The North Korean government announced possible plans this week to field another satellite into orbit by mid-June. This comes after a public visit by leader Kim Jong Un and his daughter Kim Ju-Ae to a DPRK National Aerospace Development Administration (NADA) aerospace facility earlier this month. Kim “approved the future action plan of the preparatory committee,” according the Korean Central News Agency, and said that the satellite was “an urgent requirement of the prevailing security environment of the country.”

The European Space Agency’s latest third generation Meteosat-I 1 weather satellite shows its stuff, with more to come.

You’ve never seen the Earth and its complex weather systems like this. The European Space Agency (ESA) recently unveiled views from their latest weather satellite in geostationary (GEO) orbit, Meteosat Third Generation Imager-1 (MTG-I 1).

Be sure to set your alarm for early Wednesday morning, as the Moon occults the King of Planets.

If you watch the sky long enough, even the most improbable events are bound to coincide. Just such a strange occurrence happens this Wednesday morning, when the Moon occults (passes in front of) Jupiter as seen from our Earthly vantage point… with a bizarre telescopic twist.

May 5th’s ‘Teaser’ Lunar Eclipse

A ‘barely there’ lunar eclipse will flirt with the shadow of the Earth Friday evening.

Out watching the Full Flower Moon Friday night? If you’re in the correct hemisphere, you might notice that the shade and hue of the Moon is a bit off its usual pearly white, especially along one edge.

It’s not your imagination: a subtle ‘penumbral lunar eclipse’ is indeed underway, as the Moon passes through the bright outer shadow edge of the Earth.
