Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: This could be the view from an exoplanet orbiting around a red dwarf star, but it is our own Sun. This image of was taken on July 22, 2026, in the Okanagan region in the Canadian province of British Columbia. Wildfire smoke from the Pacific Northwest acted as a solar filter, allowing the photographer to take this photo of the Sun directly. Several sunspots are also visible in this eerie image; just below and right of the center is AR 4493, a fast evolving, giant active solar region and sunspot group. The smoke is made of tiny particles that help block and scatter light with bluer colors, so the light we see coming from the Sun is dimmer and redder than usual (but it is never safe to stare directly at the Sun). Sunsets and sunrises are also more colorful because of the smoke. Some 6 billion years from now, the Sun will actually start to turn redder as it approaches its red giant phase.

Stewart Island/Rakiura is the third-largest island in New Zealand, diminutive in comparison to the country’s North Island and South Island. Yet it hosts a population of one of the largest of the kiwi: the Stewart Island tokoeka. This flightless bird, a subspecies of the Southern brown kiwi (Apteryx australis), numbers in the thousands on the island, dwarfing its human population of approximately 500.
The avian national icon is just one slice of the natural riches on Stewart Island/Rakiura, a roughly triangular piece of land about 30 kilometers (19 miles) south of the South Island. Rakiura National Park covers about 85 percent of the bright green island. And as the Māori name—Rakiura, meaning “glowing skies”—suggests, it’s a prime location for viewing the aurora australis.
On the northern half of the island, podocarp and hardwood forests featuring coniferous trees with ancient lineages blanket the land. Other areas are covered in shrublands and wetlands, as well as coastal dunes such as those lining Mason Bay. A diversity of birdlife, including the kiwi, populates these relatively untouched ecosystems. The tall trees of the podocarp forests produce various fruits attractive to avian inhabitants, such as bellbirds, with their pure-toned calls, and the rare kākāpō, the world’s heaviest and only flightless parrot species.
One notable haven for birds lies on Ulva Island, located within the inlet near Halfmoon Bay (Oban). Rats, which once preyed on bird eggs and chicks there, were deemed eradicated in 1997, and the island has mostly remained free of non-native predators. Conservationists have since embarked on a project on the much larger Stewart Island/Rakiura to eliminate rats, possums, feral cats, and hedgehogs.
When darkness falls, Stewart Island/Rakiura’s human denizens can look skyward for the chance to observe stars, auroras, nearby dwarf galaxies, and other features of the Southern Hemisphere night sky. In 2019, the remote and sparsely inhabited island was designated an International Dark Sky Sanctuary.
Amateur astronomers there and in other places with good night-sky views might search for objects of interest through Hubble’s Night Sky Challenge. In May, when this image was acquired, targets imaged by NASA’s Hubble Space Telescope that were also visible from Earth’s southern latitudes included a star cluster called the Jewel Box and a peculiar elliptical galaxy known as Centaurus A, which may have resulted from two galaxies colliding.

The NASA Innovative Advanced Concepts (NIAC) program has created 18 new awards to support visionary ideas to improve aerospace technologies in areas ranging from the exploration of the solar system to understanding the universe.
The 18 NIAC Phase I awards total $3.2 million. Each award provides up to $175,000 for a nine-month initial investigation. The NIAC projects are about early-stage concept development and are not considered official NASA missions.
“NASA has outlined an ambitious vision for the future of space exploration, we’re returning the Moon to stay, advancing to Mars, and pushing to deepen our understanding of space,” said Greg Stover, director of the Advanced Research and Technology division within the Research and Technology Mission Directorate at NASA Headquarters in Washington. “Achieving that will require more than incremental technological advancement. It means we need great leaps. These awards are the kinds of innovation the world needs NASA to help foster.”
As an innovation incubator, NIAC funds early development of potential breakthrough technologies. Concepts for award consideration must have both transformative potential and possible feasibility for eventual implementation.
“Every innovation, every leap in technology, starts with a seed of an idea,” said Phillip Williams, NIAC’s acting program executive. “The NIAC program allows NASA to germinate those seeds and determine if there’s something that could be grown to benefit future space missions and our nation’s aerospace economy.”
As NASA and its partners push for sustained lunar presence, some of the 2026 awardees focused on ways to help explore the Moon and build infrastructure there. These include a system to support hovering robots to explore lava tubes under the Moon’s surface, a method to manage temperatures for small mobile exploration robots, and a way to incorporate radioisotopic heat sources into suits to help keep astronauts warm when operating in the Moon’s nearly two-week-long lunar nights.
Other concepts focus on exploring some of the solar system’s most remarkable features. Venus, with its hot atmosphere, presents an imposing challenge for research vehicles, so one NIAC awardee explores methods for hardening instruments for longer missions.
Two other concepts could help study planetary rings. One would use a swarm of 10,000 tiny satellites to map and analyze the rings of Saturn, while another would create a system for collecting samples from rings such as those circling Saturn, Uranus, and Neptune.
Some NIAC awardees will look far beyond the solar system, exploring ways to power interstellar spacecraft, map out continents on exoplanets, observe the photon rings around black holes, and detect subtle gravitational waves to explain how galaxies formed. Others will work to answer questions directly related to life on Earth, like the potential use of spaceborne dust to reduce solar radiation, and awareness about the debris orbiting Earth.
Researchers, known as NIAC Fellows, will investigate their concepts and identify potential challenges and opportunities for further development.
The 18 selections for 2026 NIAC Phase 1 grants are:

On Wednesday, Aug. 12, a total solar eclipse will be visible in parts of Greenland, Iceland, northern Russia, the Atlantic Ocean, Spain, and a small corner of Portugal. NASA will stream the eclipse live with views across the path and interviews with subject matter experts through a variety of platforms.
Learn where to watch online:
Viewers in other places in the Northern Hemisphere also will have the chance to experience a partial solar eclipse, including parts of the U.S. (from Alaska to North Carolina), most of Canada, much of Europe, and northwestern Africa.
During the eclipse, NASA will conduct experiments in the path of totality. To investigate the dynamics of the Sun’s corona, a NASA-funded science team will chase the Moon’s shadow with a WB-57 high-altitude research aircraft. The NASA-supported Nationwide Eclipse Ballooning Project is sending students from several U.S. universities to Iceland and Spain to launch scientific balloons before, during, and after the eclipse to research how the temporary darkening of our skies during the eclipse affects Earth’s atmosphere.
NASA’s eclipse coverage is as follows (all times Eastern):

NASA’s Curiosity Mars rover captured this sand-capped butte, nicknamed “Miraflores,” estimated to be about 20 feet (6 meters) tall, with its Mast Camera, or Mastcam, on June 11, 2026, the 4,923rd Martian day, or sol, of the mission. The butte was left behind as surrounding rock eroded away over time, deepening the broad valley Curiosity is climbing through.
The surrounding area includes an expanse of terrain covered in surface features called polygons.
The panorama is made up of 11 individual images that were sent to Earth and stitched together. The color has been adjusted to match lighting conditions as the human eye would see them on Earth.
Curiosity was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASA’s Science Mission Directorate in Washington as part of NASA’s Mars Exploration Program portfolio. Malin Space Science Systems in San Diego built and operates Mastcam.
