Captured by the multispectral imager instrument, this is an enhanced-color view of the large double-ring crater Huygens and the surrounding heavily cratered southern highlands near 15° south latitude.

.

Captured by the multispectral imager instrument on NASA’s Psyche mission, this is an enhanced-color view of the large double-ring crater Huygens (upper left; about 290 miles, or 470 kilometers, in diameter) and the surrounding heavily cratered southern highlands near 15 degrees south latitude. The various colors in this dramatic scene are likely due to differences in the compositional properties of dust, sand, and bedrock in this ancient terrain. The image scale is around 2,200 feet (670 meters) per pixel.

The image was acquired with Imager A on May 15, 2026, at about 1:18 p.m. PDT, shortly after closest approach with the planet. The images have been processed into an enhanced-color view (to bring out color details beyond what the human eye can see) using red, green, and blue data from imager filters.

​A new neural-net analysis of faint stars observed by TESS just identified another 10,090 potential planets!

When they're confirmed (and most of them probably will be), they will more than double the number of known worlds beyond Earth.

.

To date, astronomers have confirmed the existence of just under 6,300 exoplanets. New research could more than double that number, adding a potential 10,000 new planets in one fell swoop.

Yes, that’s right. A 1 with 4 zeros.

The T16 project has announced the discovery of 10,091 exoplanet candidates observed by NASA’s Transiting Exoplanet Survey Satellite (TESS). Since 2018, the all-sky survey has been monitoring more than 200,000 nearby stars using the transit method, which detects the faint dip in a star’s light when a planet crosses in front of it. Astronomers typically require 3 dips to be sure that what they’re seeing is actually a planet and not a one-off event such as an asteroid or comet in that distant star system.

The T16 project analyzed the light curves of more than 54 million stars observed during the first year of the TESS mission. The project’s analysis technique allowed it to search for planets around stars up to 16 times fainter than TESS typically searches, drastically increasing the field of discovery.

.

Their pipeline detected 11,554 planet candidates. Of those, 1,052 of those had been detected previously and 411 only had one transit—not enough to confirm a planet.

That leaves 10,091 potential new planets. That’s more than were detected in the entirety of NASA’s Kepler mission and its follow-on K2 and more than double the existing planet candidates from TESS that await confirmation. These discoveries will be published in the Astrophysical Journal Supplement.

All of the new planet candidates orbit their stars quickly, with orbital periods between 12 hours and 27 days. Although most of the stars that TESS observes are smaller and cooler than the Sun, those close orbits likely mean that most of those planets are far too hot to be habitable.​

This view of the whole sky was constructed from 96 TESS sectors. By the end of September 2025, when the last image of this mosaic was captured, TESS had discovered 679 exoplanets (blue dots) and 5,165 candidates (orange dots). The glowing arc running through the center is the plane of the Milky Way. The Large Magellanic Cloud can be seen along the bottom edge just left of center. Black areas within the oval indicate regions TESS has not yet imaged. NASA/MIT/TESS and Veselin Kostov (University of Maryland College Park)​

.

NASA’s TESS (Transiting Exoplanet Survey Satellite) has released its most complete view of the starry sky to date, filling in gaps from previous observations. Nearly 6,000 colored dots scattered across the image show the locations of either confirmed or candidate exoplanets — worlds beyond our solar system — identified by the mission as of September 2025 at the end of TESS’s second extended mission.

“Over the last eight years, TESS has become a fire hose of exoplanet science,” said Rebekah Hounsell, a TESS associate project scientist at the University of Maryland Baltimore County and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It’s helped us find planets of all different sizes, from tiny Mercury-like ones to those larger than Jupiter. Some of them are even in the habitable zone, where liquid water might be possible on the surface, an important factor in our search for life beyond Earth.”

The TESS mission scans a wide swath of the sky, called a sector, for about a month at a time using its four cameras. These long stares allow the spacecraft to track the brightness changes of tens of thousands of stars, looking for variations in their light that might come from orbiting planets.

Researchers assembled an all-sky mosaic made of 96 sectors observed between April 2018, when TESS began its work, and September 2025.​

This observation is part of a long-running image campaign to aid in the classification and volume estimates of dunes in the U.S. Geological Survey global dune database. Sand dunes are among the most widespread wind features present on Mars. An earlier image from 2017 showed intresting height vs. ripple wavelength trends, but we need a digital terrain model to assess.

15-34-metre asteroid 2026 JH2 will pass ~91,000 kilometers (56,500 mi) from the Earth at 21:57 Universal Time (UT)/5:57 PM EDT. This is about a quarter of the Earth-Moon distance, and just over twice as far as geosynchronous orbit. Here's a capture of the inbound space rock from the 16th.

The building-sized asteroid will reach +11th magnitude at closest approach. Astronomer Gianluca Masi will feature the asteroid pass live tomorrow starting at 19:45 UT - Will work out more sighting ops for this one this afternoon.​

Keep in mind, the path is only approximate, as parallax comes into play on a close pass. Serious asteroid trackers should use NASA’s Horizons System for fine pointing. Good hunting! ssd.jpl.nasa.gov/horizons/​

On 18 May 2026, the near-Earth Asteroid 2026 JH2 will have an extremely close, but safe, encounter with us, coming at 91.000 km from the Earth, about 24% of the average lunar distance. The Virtual Telescope Project will show it to you live!

.

The near-Earth asteroid 2026 JH2 was discovered by the Mt. Lemmon Survey on 10 May 2026 and announced two days later. Its diameter in supposed to be in 15 – 34 meters range, while the minimum distance from us will be reached on 18 May 2026, around 21:57 UTC, when this rock will be at 91.000 km from the Earth (source: Nasa/JPL). That is 24% of the average lunar distance.

The Virtual Telescope Project will show it live, online, just before the fly-by time, when it will be peaking in brightness, around magnitude 11.5, easy to see even with a small telescope. This way, you can have a look from the comfort of your home.

The live feed will start on 18 May 2026 at 19:45 UTC.​

​ " ​This image shows Comet C/2025 R3 (PANSTARRS) crossing the Orion over four nights in May 2026 from dark-sky locations near Canberra, Australia. The sequence captures the comet gradually fading after perihelion as its ion tail becomes fainter and more diffuse over time.

The widefield background is a multi-night panorama of the Orion region, featuring Barnard’s Loop, M42, the Horsehead Nebula, and surrounding molecular clouds. Due to weather limitations, the four comet positions were captured from two locations near Canberra and later aligned to the surrounding star field to preserve the comet’s relative motion across the sky.

I spent around eight nights outside after work over the past two weeks trying to capture Comet C/2025 R3. I even met some amateurs by chance on some nights. This is, in many ways, my very first deep-sky astrophotography project after spending time learning astrophotography, and definitely not an easy one for me (lots to improve!). There were many new techniques and skills to learn, along with unstable weather on several nights. Despite all the challenges, seeing the comet gradually move through Orion over multiple nights was honestly quite magical! Clear skies!

EXIF:

Dates: May 7, 9, 11, and 12, 2026 (corresponding to the comet positions from lowest to highest in the image).

​Locations: Colinton, NSW, Australia (near South Canberra) for the two lower comet positions, and Gundaroo, NSW, Australia (near North Canberra) for the two upper comet positions.

​Gear: Benro Polaris + Canon R5 + Canon EF 135mm prime lens. RGB: f/2.0–2.2, ISO1600, multiple 30s exposures over multiple nights (plus several 5s and 2s exposures for M42 core).

​Ha: f/2.0–2.2, ISO1600–6400, multiple 30s exposures over multiple nights. Processed using PixInsight, Sequator, RegiStar, and Photoshop​ "

1,700 frames of Himawari-8 satellite data from IR bands 8, 9 & 10 spanning 4 days from 30th December 2019 are repaired, remastered, resized & retimed to create the 4k video footage in this film. Highest fidelity raw data is used to preserve quality during production. A method called frame interpolation is used to calculate the extra video frames required to create smooth motion.

To create an experience free from distraction all gaps in the data need to be repaired. Missing frames from each daily image sequence for each IR band are created. Missing sections from each daily image sequence for each IR band are patched using surrounding data.

​Visual artifacts that detract from the desired outcome are repaired. The full sequence for each IR band is assigned to a color channel and processed to arrive at the final look. Intermediate sequences are produced to consolidate repaired & processed sequences and to assist with frame interpolation method used to create Ultra High Definition video footage.
