Astrophotographer Greg Meyer has captured a striking cosmic vista featuring the grand design spiral galaxy M81 alongside the nearby 'Cigar Galaxy' (M82), against the faint swirling mass of an integrated flux nebula (IFN).
The stunning image shows the classic spiral swirl of M81 — also known as Bode's Galaxy — suspended against the chaotic cloud patterns of the nebula, with the Cigar Galaxy lurking to its left. The nebula featured in Meyer's photo is much closer to Earth than the galactic duo, and is illuminated not by starlight from within, but solely by the ambient light of the Milky Way. As a result, IFNs tend to be very faint, and challenging to capture, especially when framed alongside brighter objects.
"I always admire shots with IFN. The Texas Star Party gave me the opportunity to get a lot of Lum data under dark skies to finally get my version of the classic couple," Meyer told Space.com in an email. "A bit of trick stretching the IFN data, and not blowing out the galaxies - masks!" Meyer continued, referring to a digital editing tool used to isolate and adjust specific parts of an image.

Bode's Galaxy and M82 are found about 12 million light-years from Earth in the constellation Ursa Major. The pair are thought to have collided some 10 million years ago, with the gravitational tug of war distorting M82 into its current cigar-like shape, while prompting an explosion of starbirth, according to the European Space Agency.
The Garland Galaxy (NGC 3077) can also be spotted as a blur of light towards the bottom of the image, while a fourth galactic interloper — NGC 2976 glows to the upper right of the cosmic vista.
Meyer captured the scene over a total of 51 hours and 40 minutes using a Radian Raptor 61mm telescope paired with an ASI 2600 MM astronomy camera during the Texas Star Party astronomy event, which was held under dark sky conditions in April.
About 30 of those hours were dedicated to gathering luminance data, with the remaining time split between red, green, blue and hydrogen-alpha filter exposures. The collected light data was then processed into a single image using the astronomy software PixInsight, Photoshop and Lightroom.

Canadian, European space agencies reaffirm relations amid political, economic anxiety
LONGUEUIL - The Canadian and European space agencies say economic and geopolitical turmoil are forcing them to work closer together. Leaders at both organizations signed a joint statement today at Canadian Space Agency headquarters south of Montreal reaffirming their co-operation. Josef Aschbacher, director general of the European Space Agency, says space programs are having to contend with economic uncertainty and global conflicts. His visit comes as the United States is pressuring NATO members to increase their spending on defence — a sector of the economy that is tightly linked to space. As well, Aschbacher says the United States' space agency — NASA — could be facing deep budget cuts. Canadian Space Agency president Lisa Campbell says that in uncertain times it's important to reaffirm relationships with like-minded allies. This report by The Canadian Press was first published June 6, 2025.

Why does NASA's Perseverance rover keep taking pictures of this maze on Mars?
When you buy through links on our articles, Future and its syndication partners may earn a commission. If you've spent any time perusing the carousel of raw images from NASA's Perseverance Mars rover, you might have stumbled across an odd subject: a tiny, intricate maze etched into a small plate, photographed over and over again. Why is the Perseverance rover so obsessed with this little labyrinth? It turns out the maze is a calibration target — one of 10 for Perseverance's Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals instrument, otherwise known for its fun acronym, SHERLOC. This Sherlock Holmes–inspired tool is designed to detect organic compounds and other minerals on Mars that could indicate signs of ancient microbial life. To do that accurately, the system must be carefully calibrated, and that's where the maze comes in. Located on the rover's seven-foot (2.1-meter) robotic arm, SHERLOC uses spectroscopic techniques — specifically Raman and fluorescence spectroscopy — to analyze Martian rocks. In order to ensure accurate measurements, it must routinely calibrate its tools using a set of reference materials with specific properties. These are mounted on a plate attached to the front of the rover's body: the SHERLOC Calibration Target. "The calibration targets serve multiple purposes, which primarily include refining the SHERLOC wavelength calibration, calibrating the SHERLOC laser scanner mirror, and monitoring the focus and state of health of the laser," Kyle Uckert, deputy principal investigator for SHERLOC at NASA's Jet Propulsion Laboratory, tells The target is arranged in two rows, each populated with small patches of carefully selected materials. The top row includes three critical calibration materials: aluminum gallium nitride (AlGaN) on sapphire discs; the UV-scattering material Diffusil; and Martian meteorite SaU008, whose mineral makeup is already known and helps align wavelength calibration with real Martian geology. This is also where you'll find the maze. Why a maze? "SHERLOC is all about solving puzzles, and what better puzzle than a maze!" says Uckert. The purpose of the maze target is to calibrate the positioning of the laser scanner mirror and characterize the laser's focus, which requires a target with sharply contrasting spectral responses. The maze serves this purpose well." The maze is made of chrome-plated lines just 200 microns thick (about twice the width of a human hair) printed onto silica glass. "There are no repeating patterns and the spectrum of the chrome plating is distinct from the underlying silica glass," says Uckert. That makes it possible to measure the laser's focus and accuracy with extreme precision. If you look closely at the maze, you'll also notice a Sherlock Holmes portrait right at the center. While it's a cheeky nod to the instrument's name, it serves a practical function. "SHERLOC spectral maps can resolve the 200 micron thick chrome plated lines and the 50 micron thick silhouette of Sherlock Holmes at the center of the maze," Uckert notes. Like the portrait, the bottom half of the SHERLOC Calibration Target also serves a dual purpose: spectral instrument calibration and spacesuit material testing. It contains five samples of materials used in modern spacesuits, including some materials you might be familiar with, like Teflon, Gore-Tex, and Kevlar. And don't miss the "fun" target in this row — there's a geocache marker backing a polycarbonate target, and it does indeed have a tie-in to Sherlock Holmes. RELATED STORIES: — Perseverance rover's Mars samples show traces of ancient water, but NASA needs them on Earth to seek signs of life — Perseverance Mars rover finds 'one-of-a-kind treasure' on Red Planet's Silver Mountain — Perseverance Mars rover becomes 1st spacecraft to spot auroras from the surface of another world These materials are actively being tested under Mars conditions to determine how they hold up over time in situ, which is crucial for planning human exploration of the Red Planet. "Note that we use all of these materials to fine-tune SHERLOC," adds Uckert. "As a bonus, the spacesuit materials support unique science that will help keep future astronauts safe." Now, if all these Sherlock Holmes–related Easter eggs on the SHERLOC Calibration Target aren't enough for you, there's one final link. SHERLOC has a color camera as part of its instrumentation suite that sometimes images the target, and it's called the Wide Angle Topographic Sensor for Operations and eNgineering. Yes, SHERLOC's sidekick is called WATSON.
