Auroras from Space

 

What do auroras look like from above? Behold! From the ground, auroras dance high above clouds, frequently causing spectacular displays. From space, they look a bit different. As the International Space Station (ISS) circles the Earth every 90 minutes, it sometimes sees auroras below that are active on the night side. A one-hour time-lapse video showing auroras from above was captured about two weeks ago from the orbiting ISS. The ISS and all objects in low Earth orbit will pass well above green auroras but just a bit above red glowing auroras. The auroras' electron and proton streams are too thin to be a danger to the ISS, just as clouds pose little danger to airplanes. From orbit, as magnetic fields change, auroras can appear to squiggle and crawl like giant snakes. The featured one-minute video was captured by French astronaut Sophie Adenot of the ISS Expedition 74 crew.

An Exciting Week of Skywatching: New Moon and Perseid Meteor Shower Begin

Last updated: July 13, 2026

 

Skywatchers are in for an exciting week as celestial events unfold, marked by the transition from a new moon to a delightful crescent and the commencement of the annual Perseid meteor shower.

Starting with a new moon on Tuesday, July 14, this week brings numerous opportunities to explore the night sky.

 

The new moon will occur at 5:43 a.m. EDT, positioning the moon between Earth and the sun with its illuminated side facing away from us.

This alignment creates excellent conditions for deep-sky observation, particularly after midnight when the Milky Way becomes visible from rural areas devoid of light pollution.

 

As the week progresses, star-gazers can look forward to the waxing crescent moon making its appearance on Wednesday, July 15.

About 45 minutes after sunset, a 4%-lit crescent moon will shine brightly in the western sky. This night also presents a chance to observe “Earthshine,” a subtle glow seen on the moon’s dark side due to sunlight reflecting off Earth and back to the lunar surface.

 

By Thursday, July 16, the moon will be two days old and 10% illuminated, still visible low in the west at dusk.

Venus will make a prominent appearance nearby, ideally positioned for those wishing to catch a glimpse of both celestial bodies. Earthshine may still be visible for keen observers.

 

Friday, July 17 marks an increase in lunar visibility, with the now 17%-lit waxing crescent moon appearing to the left of Venus as darkness falls.

Venus will continue to be a striking evening object throughout the summer, drawing the eyes of amateur astronomers.

 

The much-anticipated Perseid meteor shower begins during this week, running from July 17 through August 24. However, the peak viewing will occur on the night of August 12-13 under optimal dark skies.

Generated by debris from Comet Swift-Tuttle, the Perseids are known for their vibrant, fast-moving meteors and occasional fireballs.

Under ideal conditions, observers could expect to see an impressive 60 to 100 meteors per hour after midnight, with the best rates occurring just before dawn.

 

This year’s Perseid display is anticipated to be particularly spectacular.

With the absence of moonlight interfering with visibility, and coinciding with a total solar eclipse visible in parts of Greenland, Iceland, and Spain, this event promises to be memorable for skywatchers, especially those who venture away from urban light pollution.

 

For those looking to enhance their stargazing experience, observing the waxing crescent moon as it transitions from a slim crescent to a half-lit orb provides a rewarding opportunity.

After the sunset on Wednesday, viewers will notice the moon’s gradual ascent and brightening as it moves eastward against the backdrop of stars, completing its orbit around Earth in roughly 27 days.

 

Additionally, the constellation of the week is Lyra, known as The Harp. This small constellation, characterized by a parallelogram of faint stars, includes Vega, one of the brightest stars in the sky.

Vega has historical significance, having served as the pole star 12,000 years ago and projected to regain that title in another 12,000 years. Vega’s brightness also sets the standard for measuring other stars’ luminosity.

 

As these celestial wonders unfold, amateur astronomers and stargazers alike are encouraged to embrace the beauty of the night sky, armed with the knowledge of the moon’s phases and the mesmerizing display of the Perseids.

For those seeking precise observational guidance, consulting online planetariums like Stellarium can enhance the overall experience.

NASA’s Hubble Discovers First of Star Cluster’s Missing Black Holes

Jul 13, 2026

 

The massive globular star cluster Omega Centauri has puzzled astronomers for decades. It should be filled with black holes left behind by exploding stars, yet evidence for them is scarce.

Now, astronomers using archival data from NASA’s Hubble Space Telescope and supportive observations from NASA’s James Webb Space Telescope have finally located their first stellar-mass black hole in this cluster.

Discovering the first of this missing black hole population will help refine current theories on black hole formation within environments such as Omega Centauri. The team’s findings published Monday in The Astrophysical Journal Letters.

 

Omega Centauri is composed of 10 million gravitationally bound stars.

Though the astronomical community previously found evidence with Hubble that an intermediate-mass black hole lurks at its center, models suggest this star cluster should also contain about 10,000 smaller, stellar-mass black holes.

This notable population of black holes evaded detection in previous observational studies, which used the radial velocity method or looked for radio and X-ray emission from material falling onto black holes.

 

This new discovery features a different approach, known as astrometry, to measure very small movements of stars over time.

By sifting through more than 20 years of Hubble archival data and pulling in recent Webb data to further refine their astrometric measurements, the team located a star orbiting an invisible object so hefty that it has to be a black hole.

Dubbed oMEGACat BH-2, it is the first stellar-mass black hole detected in Omega Centauri, and it has some surprising qualities. oMEGACat BH-2 has a lower-than-expected mass and, with its visible star companion, the black hole-star duo has the longest orbital period of any black hole binary system known to date.

 

“With Hubble and Webb data, we were able to see the motion of the visible main sequence star that is part of this binary, which is about 18,000 light-years away in the dense environment of Omega Centauri,” said Matthew Whitaker of the University of Utah, Salt Lake City, lead author of the paper.

“The precision of these measurements is incredible, down to a fraction of a pixel on Hubble and Webb’s detectors. It would not have been possible to find this black hole without these two space telescopes.”

The team’s findings refine a past study by a different group of scientists that suggested this binary system included a neutron star.

By expanding Hubble data from the earlier investigation with archival Hubble astrometric measurements from 2002 to 2023, and pulling in Webb near-infrared data to improve precision, the University of Utah-led team was able to better constrain the mass of the visible star’s dark companion, ruling out the neutron star possibility.

 

“While we already knew that the star was 0.78 solar masses, we can now calculate the black hole’s mass, which is 4.46 solar masses and therefore too heavy to be a neutron star.

However, its mass is much lower than would be expected in a metal-poor environment like Omega Centauri. This is surprising and exciting,” said Anil Seth of the University of Utah, a coauthor of the study.

“We now know that a metal-poor star is able to form a black hole like this, and we need to figure out how that happens. This detection is providing some data to those who do that kind of modeling.”

 

Long time coming

Based on the precise data from Hubble and Webb, the team could chart the star’s path over 20-plus years, during its closest approach to its black hole companion when it moved the fastest across the sky.

From the extensive data, the team determined that the visible star orbits oMEGACat BH-2 once every 94 years, making it the longest-period black hole binary ever known.

 

Its long orbital period also gives a clue to the origin of this binary system. It was probably dynamically formed, meaning the star and its black hole companion did not start out together but rather found each other in this cluster.

The researchers calculated that a system like oMEGACat BH-2 will survive for less than a billion years before it is torn apart by encounters with nearby stars, a much shorter span than the age of the cluster (approximately 12 billion years old).

 

“It's important to understand black hole populations in globular clusters because there's uncertainty about their physics and formation,” said Seth.

“More specifically, understanding the process of forming black holes and then dynamically forming binaries is vital, because it affects our ability to interpret and understand gravitational wave events.

Environments like Omega Centauri are the primary places where we think binaries are merging and creating these waves.”

 

The team’s discovery of stellar-mass black hole oMEGACat BH-2 with the Hubble-Webb dataset is just the start of finding these evasive black hole populations in globular star clusters.

 

“With Hubble and Webb, we can continue to look at Omega Centauri and expand our search for similar systems within other clusters,” said Whitaker.

“We’re also very excited for the launch of NASA’s Nancy Grace Roman Space Telescope because it will image the crowded galactic bulge, including the galactic center, very regularly with Hubble-like resolution and with a much wider field of view.

We’re hoping we’ll be able to find black hole binary systems like this one because of the regular cadence of Roman’s observations.”
