When To See Mars As A ‘Cherry' On The Moon This Weekend In Rare Event
Skywatchers across the globe are in for a treat this weekend as the moon and Mars meet in a stunning close conjunction — what some astronomers call a celestial 'kiss.' The rare pairing, best viewed just after sunset on Sunday, June 29, will offer one of the most striking naked-eye sights of the summer. In an alignment of celestial bodies, Mars was captured here rising out of a lunar occultation on 13 ...

KPNO/NOIRLab/NSF/AURA/J. Winsky On Sunday, June 29, the moon and Mars reach conjunction, appearing less than 0.2 degrees apart. For most viewers, Mars will seem like a reddish 'cherry' perched above a spectacular 24%-lit waxing crescent moon. The duo will be above the western horizon shortly after sunset and remain easily visible, if skies are clear, for about an hour. A conjunction is an astronomical term for when two or more objects shine close together in the night sky, as seen from Earth. They are line-of-sight illusions. From the Pacific Ocean close to northern South America, the moon will briefly occult Mars, something that was seen from North America on Jan. 13. Sunday, June 29: Moon And Mars In Conjunction Stellarium In a warm-up to the main event, on Saturday, June 28, the 16%-lit waxing crescent moon will appear — also above the western horizon around 45 minutes after sunset —below and to the right of Mars. In between the two will be the blue star Regulus, the brightest star in the constellation Leo, 'The Lion.' The striking trio will appear almost evenly spaced in the sky, creating a near-perfect line. Saturday, June 28: Moon, Regulus And Mars Stellarium Following the close conjunction, the crescent moon will continue climbing higher in the sky over the next few nights, pulling away from Mars and Regulus. By Monday, June 30, the moon will be 33%-illuminated and will still form a beautiful visual line-up with Mars and Regulus. Planetary Conjunctions Coming Soon The next major planetary conjunctions will see Venus and Jupiter appear to be just 2.4 degrees apart before sunrise on Aug. 12 and a crescent moon and Venus just 0.8 degrees apart before sunrise on Sept. 19.

Watch the stunning Mars and Regulus conjunction today with this free livestream
When you buy through links on our articles, Future and its syndication partners may earn a commission. Mars and the star Regulus are set to put on a dazzling show tonight as the Red Planet passes remarkably close to Leo's brightest star in a striking celestial pairing — and you can watch it live online. The conjunction between Mars and the bright blue star Regulus began on Monday (June 16) and will bring the two objects side by side in the night sky. A conjunction occurs when two celestial bodies appear very close together from our perspective on Earth. Using its robotic telescopes in Manciano, Italy, the Virtual Telescope Project is offering a free online livestream (weather permitting) of the conjunction beginning at 3:45 p.m. EDT (1945 GMT) today (June 17). You can watch the livestream here on courtesy of the Virtual Telescope Project or directly on their WebTV page or YouTube channel. At their closest point, Mars and the bright star will be just 0.7 degrees apart — roughly the width of your little finger held at arm's length against the night sky — which is incredibly close for two celestial objects. The pair will remain in close visual proximity through Wednesday night (June 18). During conjunction, both Mars and Regulus — the 21st brightest star in the night sky — will shine at 1.4 magnitude. Although virtually equal in brightness, the two celestial objects differ dramatically in color. "They will offer a superb show, offering very different colours: Mars will bring its legendary red hue, while Regulus will shine like a blue diamond," Gianluca Masi, Virtual Telescope Project founder and astronomer, told in an email. Although Mars and Regulus will look strikingly close, it's just a trick of perspective from our viewpoint on Earth. In reality, Mars lies within our solar system about 171 million miles away, while Regulus is nearly 80 light-years from us in the constellation Leo, the Lion. Nonetheless, the pair will appear close and bright enough in the night sky to be seen by the naked eye. For a more detailed view, binoculars or a small telescope with low magnification can be used, Masi said. The best time to catch Mars and Regulus — known as the "Heart of the Lion"— will be just after twilight fades and the stars become visible under clear, dark skies. Viewers can look toward the western sky, near the constellation Leo, to spot the dazzling pair meet up.

Starwatch: Mars and Regulus will make for an eye-catching pair
Look into the western sky this week to see an eye-catching conjunction between Mars and Regulus, the brightest star in the constellation of Leo, the lion. The chart shows the view from London at 2300 BST on 16 June 2025. The pair of celestial objects will be separated by less than a degree, less than twice the apparent diameter of the full moon. This means that as well as being an easy spot with the naked eye, they are close enough to fit into the same field of view when viewed through binoculars. Although they will move further apart as the week continues. The colour difference between them will be striking. Mars will be red whereas Regulus shines with a blue-white colour. Regulus is the 21st brightest star in the night sky and lies about 79 light years away from us. It contains just over four times the mass of the sun, and has a diameter just over four times larger, too, giving out about 340 times the sun's energy. From the southern hemisphere, too, the conjunction appears in the north-north-west. In addition, on 19 June, the moon will be close to Saturn in the constellation Pisces, the fishes.

Red Meets Blue: Don't Miss The Rare Mars-Regulus ‘Kiss' This Week
For three successive nights, beginning Monday, June 16, the red planet Mars will be positioned next to the bright blue star Regulus, creating a rare contrast in colors in the night sky. Mars and Regulus will be in a close conjunction next week. At their closest point, the two celestial bodies will appear to be just 0.7 degrees apart. That's about the same as a little finger held at arm's length against the night sky. As conjunctions go, that's incredibly close. To add to the spectacle, both Mars and Regulus will shine at 1.4 magnitude. Regulus is the 21st brightest star in the night sky. Although virtually equal in brightness, they differ dramatically in color. The best time to catch Mars and Regulus will be just after twilight fades and the stars become visible. Although the official moment of closest approach happens Monday night, the view on Tuesday will be nearly identical, with Wednesday also offering a similar view. Monday, June 16 and Tuesday, June 17: Mars And Regulus In Conjunction Approximately 78 light-years from Earth, Regulus is hotter and younger than the sun, and it emits a blue-white light. Its name comes from Latin, meaning 'little king.' The brightest star in the constellation Leo, "The Lion," Regulus has been known since ancient times as the 'heart of the Lion.' Now past its January peak brightness, Mars is the sole survivor of the "planet parades" of early 2025. Known as the Roman god of war, it's been moving steadily closer to Regulus during June and will keep heading west across Leo in the coming nights. Although binoculars or a telescope will be required to appreciate the contrast in color between Mars and Regulus, it's rare to have such an opportunity. A similar phenomenon can be observed by pointing a small telescope at the blue and red Albireo double star, located at the head of the swan in the Cygnus constellation. Another is the brilliantly colored stars of the Jewel Box Cluster (NGC 4755) visible from the Southern Hemisphere. A Trump Administration plan to cut nearly 24% ($6 billion) from NASA's budget would see the space agency repurposed to focus solely on landing astronauts on the moon and Mars before China, according to the BBC. However, NASA's Artemis 3 mission, planned for 2027, to land astronauts on the moon utilizes a SpaceX Starship rocket. The row between Donald Trump and Elon Musk puts that in doubt. As part of the plan, which is expected to go before Congress, funding for science projects would be cut by nearly 50%, including the cancellation of NASA's plans for a Mars Sample Return mission and its involvement in the ExoMars Rosalind Franklin rover.
