NASA Astronomy Picture of the Day

July 18, 2026

Shadow and Rainbow

At sunset, an alignment of rainbow and mountain shadow was captured in this remarkable snapshot. The stunning view was recorded from a fire lookout on Smith Peak in the Plumas National Forest near Portola, California on July 13. Still, near sunset it's no accident that the majestic mountain shadow seems to point to the center of the graceful rainbow arc. Due to perspective and the long line of sight the mountain shadow naturally forms a tapering triangular shape, its apex positioned at the point opposite the Sun on the horizon. Following thunderstorms across the region, the rainbow arcs across the early evening sky, with its colorful and characteristic 42 degree arc formed as sunlight is refracted and reflected by the atmospheric water droplets. The geometric center of a rainbow arc lies at the antisolar point. And in this scene from the golden hour on planet Earth, that's also oposite the setting Sun along the distant horizon.

The Sky Today on Saturday, July 18: Comet Tempel’s knife-edge tail

July 18, 2026

Catch an edge-on comet as Tempel 2 plunges below the plane of our planet’s orbit, heading toward perihelion.

Comet 10P/Tempel (also called Tempel 2) is closing in on the Sun for an early August perihelion. It’s now undergoing some spectacular visual changes as Earth passes through the plane of the comet’s orbit.

As we pass through the plane, the comet’s tail appears to thin and spread out, turning into a line that extends to either side of the nucleus, rather than the more traditional one-sided tail we’d expect.

Tempel 2 is in an extremely favorable location, rising late in the evening and visible overnight. After the Moon sets, turn southeast and look about 20° above the horizon for 3rd-magnitude Deneb Algedi, the brightest star in Capricornus.

Tempel 2 is just 4.2° southwest of this star this evening, close to Iota (ι) Cap (about 1.5° northwest of this star). Check out our chart above to help you pinpoint its location.

Recent observations have placed the comet around 9th magnitude — an easy catch for binoculars or any scope, especially in a dark sky.

Sunrise: 5:47 A.M.

Sunset: 8:26 P.M.

Moonrise: 10:41 A.M.

Moonset: 10:58 P.M.

Moon Phase: Waxing crescent (27%)

*Times for sunrise, sunset, moonrise, and moonset are given in local time from 40° N 90° W. The Moon’s illumination is given at 10 P.M. local time from the same location.

NASA’s Psyche Mission Delivers Mars Flyby Data, Time-lapse Video

July 17, 2026 1:07PM

NASA’s Psyche spacecraft flew by Mars on May 15, using the planet’s gravity to gain speed and slightly tilt its trajectory.

The flyby also gave the team an opportunity to prep for the science they will be conducting when they reach the metal-rich asteroid Psyche in 2029.

Using Mars as a stand-in for the asteroid during the flyby, they could test the spacecraft’s science instruments. The results, downlinked and analyzed over the subsequent weeks, were impressive.

Not only did the instruments operate precisely as designed, delivering data that matches what NASA already knows about Mars, they also provided a few new insights about the planet along the way.

“The mission’s imager, magnetometer, and gamma-ray and neutron spectrometer teams worked overtime to make full use of this planetary encounter, and all instruments delivered great results,” said Lindy Elkins-Tanton, principal investigator for Psyche at the University of California, Berkeley.

“We didn’t anticipate big discoveries, given how extensively the planet has been studied, but we did complement Mars science with the data we collected through Psyche’s unique perspective.”

Peppered by Mars neutrons

The gamma-ray and neutron spectrometer, which will help scientists determine the chemical elements that make up the asteroid’s surface material, got a real workout during the flyby.

As high-energy cosmic rays bombard a planetary body, the elements on the surface absorb the energy, emitting neutrons and gamma rays of varying energy levels.

By measuring these emissions, scientists can match them to properties of known elements to determine what the body is made of.

While the flyby altitude of 2,864 miles (4,609 kilometers) was too far away to measure gamma rays from Mars, hopes were high that neutrons escaping the planet’s surface and atmosphere could be detected.

“Around the time of Mars closest approach, the neutron spectrometer detected a count-rate enhancement close to what we anticipated.

It was very gratifying to see,” said David Lawrence, the science lead for Psyche’s spectrometer at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland.

“As expected, we didn’t detect gamma rays from Mars, but we put the instrument through its paces, and it performed excellently.”

Magnetic Mars

Like the gamma-ray and neutron spectrometer, the mission’s magnetometer has been operating since the spacecraft’s journey began with its 2023 launch.

Designed to measure the asteroid Psyche’s magnetic field, the instrument will help the mission test the idea that the object is the metallic core of a planetesimal — a building block of a rocky planet.

While the instrument has constantly been measuring the solar wind’s magnetic field during cruise — including when occasional coronal mass ejections washed over the spacecraft — this is the first magnetic field signature of a celestial body that the magnetometer has measured.

“As the spacecraft passed close to Mars, the magnetometer saw an intense uptick in magnetic field corresponding to the bow shock region, where the solar wind slams into the planet’s magnetic field,” said Ben Weiss, Psyche’s deputy principal investigator and the magnetometry investigation lead at Massachusetts Institute of Technology in Cambridge.

“This flyby calibration effort validated the instrument’s performance under dynamic conditions while also revealing the fascinating physics of planetary magnetism.”

Red Planet imaging

Starting in early May and throughout the flyby, the spacecraft’s multispectral imager — a pair of identical cameras designed to photograph the surface of the asteroid in different wavelengths of light — had been delivering views of Mars to the mission’s raw image feed.

Because of the high-phase angle at which the spacecraft approached the planet, Mars initially appeared as a thin, bright crescent, with sunlight scattering through its atmosphere.

During close approach, the imager team captured detailed views of the Martian surface, including windblown craters, the south polar ice cap, and the large double-ringed Huygens crater. They’re all visible in a time-lapse video that captures the monthlong flyby sequence of images.

“The imager performed brilliantly, delivering some rarely seen views of the Red Planet,” said Jim Bell, the Psyche imager instrument lead at Arizona State University in Tempe.

“Besides the obvious beauty of the photos, we were also able to fully test its calibration and sensitivity to scattered light, including picking out the Martian moons Phobos and Deimos from very far away as a part of a practice for the satellite search that we’ll use at the asteroid Psyche to look for any moonlets there.”

To help characterize and calibrate the imager, the team is comparing flyby images with imaging data from other missions at Mars, including NASA’s Mars Reconnaissance Orbiter, 2001 Mars Odyssey orbiter, and Curiosity and Perseverance rovers, along with ESA’s (European Space Agency’s) Mars Express and ExoMars Trace Gas Orbiter, and the United Arab Emirates Mars Mission’s Hope Orbiter.

The Psyche spacecraft is now headed directly toward its target asteroid, located in the main asteroid belt between Mars and Jupiter.

“This gravity assist was years in the making, and the navigation team nailed it — Psyche flew by Mars on exactly the trajectory we needed to set us on a path to rendezvous with the asteroid in the summer of 2029,” said Bob Mase, Psyche’s project manager at NASA’s Jet Propulsion Laboratory in Southern California.

“The spacecraft is in great shape, and we’re on schedule to resume sustained thrusting with the solar-electric propulsion system later this fall.”

Week Wraps with New Crew Adjustments and Human Research Studies

July 17, 2026 12:58PM

Crew swap activities are underway aboard the International Space Station as three new crewmates continue getting up to speed with living and working in microgravity and another Expedition 74 trio prepares to return to Earth.

Meanwhile, scientific operations are back in full swing aboard the orbital outpost with lab residents studying how weightlessness affects the human body.

NASA flight engineer Anil Menon kicked off his Friday shift exploring his new surroundings in microgravity, learning how to move through the station’s modules, and familiarizing himself with lab systems and hardware.

The first-time space flyer wrapped up his first week in space swapping arm and leg components, checking the helmet, and inspecting the configuration of a spacesuit.

Roscosmos cosmonauts Pyotr Dubrov and Anna Kikina, who are each beginning their second spaceflight, took turns wearing an acoustic monitor strapped around their necks that measured their respiratory rate.

Afterward, Dubrov continued unpacking cargo from the Soyuz MS-29 spacecraft while Kikina cultured cell samples to learn how microbes adapt to microgravity.

NASA flight engineer Chris Williams, who will return to Earth at the end of July, began his day with ultrasound scans of his arteries and blood pressure checks for the CIPHER human research study.

Next, he wore a heart rate monitor and breathing gear that measured his aerobic fitness in space while pedaling on an exercise cycle and jogging on a treadmill.

Station commander Sergey Kud-Sverchkov and flight engineer Sergei Mikaev continued preparing for their return to Earth and tested the lower body negative pressure suit that reverses space-caused fluid shifts from the head toward the feet.

The specialized suit may help ease a crew member’s adjustment to Earth’s gravity after long-term spaceflight.

The cosmonauts, along with Williams, are nearing the end of an eight-month mission and are preparing their Soyuz MS-28 spacecraft for its upcoming undocking and landing in Kazakhstan.

NASA flight engineer Jessica Meir, who is staying aboard the space station until the end of summer with flight engineers Jack Hathaway of NASA, Sophie Adenot of ESA (European Space Agency), and Andrey Fedyaev of Roscosmos, continued researching how to make saline solution in microgravity using the station’s water supply.

Hathaway configured blood pressure monitoring gear then swapped cargo in and out of the Cygnus XL spacecraft.

Adenot videotaped her exercise session on the advanced resistive exercise device using a motion capture system to help researchers develop more effective workout sessions for astronauts.

Finally, Fedyaev transferred water from the Progress 94 cargo spacecraft into station tanks then assisted his cosmonaut crewmates with the lower body negative pressure suit tests.

NASA’s Chandra and IXPE Study Pulsar in Lighthouse Nebula

Jul 17, 2026

This composite image, released on July 9, 2026, shows the region around a pulsar – a neutron star with a strong magnetic field that spins incredibly fast – within the Lighthouse nebula.

The image contains X-ray data from NASA’s Chandra X-ray Observatory in purple, X-rays from NASA’s IXPE (Imaging X-ray Polarimetry Explorer) in blue, and radio emission captured by the Australia Compact Telescope Array in green.

Scientists used IXPE – for the first time ever – to directly measure the magnetic fields of the pulsar.

The results provide new insight into the structure of some of the most extreme objects in the cosmos, as NASA continues to explore the secrets of how the universe works.

A paper describing the results published July 9 in the Astrophysical Journal.
