The Perseid meteor shower begins this month.
Each month, I pick out North America's celestial highlights for the week ahead (which also apply to mid-northern latitudes in the Northern Hemisphere). Check my main feed for more in-depth articles on stargazing, astronomy, eclipses and more.
The perfect month to get out and look up in the Northern Hemisphere, July 2025 has a lot to offer. From spectacular views of Mercury, Venus, Mars, Jupiter and Saturn to a full 'buck moon' and from a rare and wonderful moon-Pleiades conjunction to no fewer than three meteor showers, here's everything else you need to know about stargazing and the night sky in July 2025:

1. Earth At Aphelion
When: Anytime on Thursday, July 3, 2025.
Where: the sun (you must use solar eclipse glasses).
Earth is today at aphelion — it's farthest from the sun in the year. It happens because Earth orbits the sun in a slightly elliptical orbit. At aphelion, Earth is 94.5 million miles (152 million kilometers) away from the sun, while in six months' time, it will be at perihelion, 91.4 million miles (147 million kilometers) from the sun. That's only about a three percent difference, but the sun today will look slightly smaller in the sky. If you have any leftover solar eclipse glasses, take a look.
2. Mars And Mercury
When: After sunset on Friday, July 4, 2025.
Where: west.
Look west 45 minutes after sunset, and you'll see Mars and Regulus above the western horizon. Mentally draw a line between them and carry on to the horizon, and you may see tiny Mercury — the "Swift Planet" — making a rare appearance.
Saturday, July 5: Venus And The Pleiades
3. Venus And The Pleiades
When: before sunrise on Saturday, July 5, 2025.
Where: northeast.
If you can rise before the sun, look to the northeast for the sumptuous sight of bright Venus beneath the Pleiades, an open star cluster that looks beautiful to the naked eye and through binoculars.
4. Venus Highest
When: before sunrise on Tuesday, July 8, 2025.
Where: east-northeast.
Venus reaches its highest point in the morning sky today during its current apparition as the bright 'Morning Star." Look to the east-northeast about 30 minutes before sunrise, and there'll be no mistaking the bright planet about 25 degrees above the horizon.
5. Full 'Buck Moon' Rises
When: moonrise where you are on Thursday, July 10, 2025.
Where: eastern horizon.
The first full moon of summer, July's buck moon, rises on the evening of July 10. Though it technically reaches full phase at 4:38 p.m. EDT, catch it at moonrise for the best views as a huge, orange orb climbs the eastern sky. This full moon will stay low due to its proximity to the summer solstice.
6. Perseid Meteor Shower Begins
When: after midnight from July 17, 2025.
Where: northeast.
While the famed Perseids peak in August, their first streaks appear around July 17. That night also features a last-quarter moon, meaning darker skies to catch a few early Perseid fireballs .
Tuesday, July 15: The Moon Meets Saturn
7. Moon Meets Saturn
When: around midnight on Tuesday, July 15, 2025.
Where: east.
Late tonight, a 70%-illuminated waning gibbous moon will rise in the east alongside Saturn. By midnight, look about halfway up the southeastern sky to see them paired just two degrees apart. Saturn will glow a steady yellowish light above the moon.
8. Moon Meets The Pleiades
When: 45 minutes before sunrise on Sunday, July 20, 2025.
Where: east-northeast.
A delicate 24%-lit crescent moon will glide alongside the dazzling Pleiades open cluster (also known as the Seven Sisters). Earthshine — sunlight reflected off Earth's oceans, ice caps and clouds — will give the moon's darkened portion a ghostly glow.
Sunday, July 20: Moon And The Pleiades
9. Crescent Moon And Mars
When: 45 minutes after sunset on Sunday, July 27, 2025.
Where: west.
With the crescent moon now 11% lit, it will be higher in the western sky after sunset than it was last night. Just to its upper left will shine Mars, past its best but still unmistakable. The mostly unlit face of the moon will be faintly illuminated by Earthshine, the ghostly glow on the moon's night side.
10. Meteor Showers Peak
When: early hours of Tuesday, July 29. 2025.
Where: all-sky.
Two overlapping meteor showers — the Delta Aquariids and the Alpha Capricornids — both reach their peak tonight. The Delta Aquariids may produce up to 20 meteors per hour, while the Alpha Capricornids can add another 5 to 10.

Fast Five Quiz: The Presentation and Diagnosis of GPA

Formerly known as Wegener granulomatosis, the granulomatosis with polyangiitis (GPA) subtype of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis can impact a variety of organ systems, often presenting with a diverse range of clinical features that complicate timely diagnosis. Knowing how to identify the symptoms and diagnose this rare disease is paramount for adequate treatment. What do you know about the presentation and diagnosis of GPA? Check your knowledge with this quick quiz. Upper and lower respiratory tract involvement, along with the skin, eyes, and nervous system (with or without kidney manifestations) are the classic presentations of ANCA vasculitis, with most common presentations of GPA being respiratory, renal, and ear, nose, and throat (ENT) symptoms. ENT manifestations are distinctive and include nasal tissue crusting, mucosal damage causing epistaxis, cartilage deterioration leading to saddle nose deformity, erosive sinus disease, and subglottic stenosis. Isolated liver involvement in GPA is considered rare. Gastrointestinal involvement can occur in patients with GPA, but it is also not common. Though neurological symptoms can be seen in patients with GPA, isolated involvement is not as common as upper and lower respiratory tract involvement. Learn more about the presentation of GPA. MRI is suggested for detecting pachymeningitis and retro-orbital lesions in patients with GPA, with researchers who have evaluated patient cases of GPA stating that the 'exploration of pachymeningitis relies on MRI.' Further, MRI is usually more effective than CT when detecting pachymeningitis. F-18-fluorodeoxyglucose PET with CT is usually used to detect occult inflammation and exclude malignancy and infection in this population; however, data have shown this method has high sensitivity for detecting cardiovascular, lung, nasal/sinus, and kidney involvements. Standard radiograph is not usually used in this setting. Learn more about imaging for GPA. The distinctive renal pathology in GPA is characterized by pauci-immune focal and segmental necrotizing and crescentic glomerulonephritis. This histological pattern features inflammatory destruction of small blood vessels with scant or undetectable immune complex deposits in vessel walls. Microscopic examination of kidney tissue typically reveals areas of fibrinoid necrosis within glomeruli and proliferative changes outside capillaries forming crescents; inflammation of small vessels with neutrophil infiltration and endothelial alterations might be observed as well. When examined with immunofluorescence techniques, the tissue shows minimal or absent staining for immunoglobulins and complement factors, confirming the pauci-immune nature of the condition. Though membranous nephropathy, minimal change disease, and lupus nephritis are types of glomerulonephritis, they are not characteristic of GPA. Learn more about renal histology in GPA. PR3-ANCA shows the strongest association with GPA. Various sources have shown that PR3-ANCA is present in approximately 80% of patients with GPA but can be positive in 2%-27% of patients with microscopic polyangiitis (MPA). Though ANCA testing offers valuable diagnostic insights, clinicians should evaluate results alongside clinical presentations and tissue examinations, since these antibodies occasionally appear in other inflammatory disorders or as medication side effects. MPO-ANCA is associated with GPA but it is not as common as PR3-ANCA. Anti-neutrophil elastase and ANTI-LAMP2 can be seen with ANCA-associated vasculitis but are not specific for GPA. Learn more about ANCA detection in GPA. The presence of lung nodules serves as a key distinguishing feature of GPA when compared with MPA. Although both conditions might present with pulmonary bleeding from capillaritis, nodular formations or cavitary nodules strongly suggest GPA rather than MPA. Conversely, pulmonary fibrosis typically appears in patients with MPA and rarely develops in those with GPA. Interstitial lung disease in an interstitial pneumonia pattern is associated with MPA.

‘Jurassic World Rebirth' Reviews: Rotten Tomatoes Critics Split On Movie

Scarlett Johansson in "Jurassic World Rebirth." Jurassic World Rebirth, Scarlett Johansson, Jonathan Bailey and Mahershala Ali's reboot of the Jurassic World franchise, has Rotten Tomatoes critics divided. Jurassic World Rebirth opens in theaters nationwide on Wednesday. The official summary for the film reads, 'Five years after the events of Jurassic World Dominion, the planet's ecology has proven largely inhospitable to dinosaurs. Those remaining exist in isolated equatorial environments with climates resembling the one in which they once thrived. 'The three most colossal creatures across land, sea and air within that tropical biosphere hold, in their DNA, the key to a drug that will bring miraculous life-saving benefits to humankind.' Directed by Gareth Edwards, Jurassic World Rebirth also stars Rupert Friend, Manuel Garcia-Rulfo, Luna Blaise, David Iacono, Audrina Miranda, Philippine Velge, Bechir Sylvain and Ed Skrein. As of Tuesday, Jurassic World Rebirth has earned a 53% 'rotten' rating from Rotten Tomatoes critics based on 113 reviews. RT's Critics Consensus and Popcornmeter rating are still pending. What Are Individual Critics Saying About 'Jurassic World Rebirth'? Among the top critics on RT who give Jurassic World Rebirth a 'rotten' rating is Johnny Oleksinski of the New York Post, who writes, 'The once-great franchise is hardly reborn from the amber this time. It's slammed by an asteroid yet again.' Alissa Wilkinson of The New York Times also gives Jurassic World Rebirth a 'rotten' rating on RT, 'In the story, the ubiquity of the dinosaurs has left humanity feeling bored and annoyed, cutting the feet out from under those moments. And it's starting to feel like the movies are getting bored, too.' Nick Schager of the Daily Beast rates Jurassic World Rebirth 'rotten' as well, writing in his RT review summary, 'he underwhelming result is similar to its signature beasts: a handsome clone that serves no purpose except to line its creators' pockets.' Mark Kennedy of The Associated Press is among the top critics on RT who give Jurassic World a 'fresh' rating, writing, 'In many ways, the folks behind Jurassic World Rebirth are trying to do the same thing as their mercenaries: Going back to the source code to recapture the magic of Steven Spielberg's 1993 blockbuster original. They've thrillingly succeeded.' Bill Bria of The Wrap also gives Jurassic World Rebirth a fresh rating on RT, writing, 'Just because cheeseburgers are now available anywhere doesn't mean that they can't be damn tasty. Jurassic Park Rebirth is just a well-made cheeseburger, and whether that's filling and interesting enough is up to your own appetite.' Also giving the film a 'fresh' review is Stephanie Zacharek of TIME Magazine, who writes, 'Jurassic World Rebirth features likable humans as well as some pleasantly cartoonish distasteful ones, and lots of dinosaurs just doing their thing.' Jurassic World Rebirth opens in theaters nationwide on Friday.

Rare cataclysmic exploding star spotted by citizen scientists

Two years ago, a team of astronomers requested help from citizen scientists around the world for the Kilonova Seekers Project. Launched in July 2023, the endeavor tasks volunteers with parsing through all-sky survey images captured daily by telescopes on opposite sides of the planet known as the Gravitational-wave Optical Transient Observer (GOTO). Within six months, Kilonova Seekers' over 2,000 volunteers contributed more than 600,000 classifications to researchers, resulting in a total of 20 new discoveries. Now, astronomers have announced the project's first major published find in Astronomy & Astrophysics: a brilliant exploding star observed in near real-time. Now known as GOTO0650, astronomers have determined the cosmic body is a cataclysmic variable star—one whose brightness increased by 2,500 times in just two days. A cataclysmic variable star isn't technically a single object. Instead, it's a compact binary system composed of a white dwarf stealing matter from a nearby donor star. Occasionally, that matter reaches a critical temperature and density inside the gas disc encircling the white dwarf, resulting in a blinding burst of light and energy. According to Kilonova Seekers Project co-lead and University of Warwick astronomer Tom Killestein, the discovery could easily have been missed among the many other night sky objects without the citizen scientists' help. 'Remarkably, public volunteers identified this star as an object of interest within 3.5 hours of the image being taken by the GOTO telescopes,' Killestein explained in a statement, adding that the involvement from volunteers 'didn't stop there.' 'There was a huge follow-up response from the public,' he continued. 'It was flagged for further observations from the Swift and Einstein Probe space observatories, and GOTO0650 was bright enough for amateur astronomers to take impressively high-quality observations of with their own equipment, which formed a key part of the paper and really [helped] us understand the object.' Thanks to the quick response from volunteers, astronomers had enough time to collect a notably complete dataset on the star that included X-ray, UV, and spectroscopy measurements along with visual observations from amateur astronomers. From these, it appears that GOTO0650 is what's known as a 'period bouncer,' a rarely spotted cataclysmic variable star in its final state. GOTO0650 is an exciting find for professional space observers, but for everyday Kilonova Seekers like Svetoslav Alexandrov in Bulgaria, it's something else entirely. 'Traffic in Sofia, Bulgaria, is always awful during the mornings so I have to pass time on the bus somehow, and contributing to citizen science is an excellent way to do that,' he said, adding that he 'literally screamed with joy' when he learned that his idle star searching would lead to a research paper co-authorship. 'I'm certain that people on the street raised their eyebrows when they saw me screaming and dancing, but I didn't care,' said Alexandrov. 'I knew I am a co-discoverer of something significant, and this was all that mattered.'
