June 13-19, 2025 Sky Watch: Mars Meets Regulus, Saturn & Moon, Venus Shines
I was just thinking about Ray Bradbury - how he had this extraordinary gift for blending the fantastical with the deeply human. (Side note: If you're somehow unfamiliar with Bradbury, he's basically the literary giant who made science fiction respectable. You know Fahrenheit 451? The Martian Chronicles? That's our guy. He brought rocket ships and time machines into the realm of "serious literature" while the literary elite weren't looking, and by the time they noticed, it was too late - everyone was already in love with his work.)
"We are an impossibility in an impossible universe," he once wrote. And doesn't that just hit you right in the existential sweet spot?
Here we are, tiny specks on a spinning rock, somehow conscious enough to look up and wonder about it all. As we dive into this week's skywatching events, I keep coming back to this feeling - this profound appreciation for the mystery, the beauty, and yes, the privilege of witnessing the cosmos unfold above us. Whether you see it as divine creation or a marvel of nature, there's something utterly humbling about staring into the vast unknown.
Stars are waiting - let's roll!
There's something downright majestic about a nearly full moon hanging in the evening sky. At 97% illumination, our lunar neighbor is serving serious celestial drama on the 13th. While not technically full, this waning gibbous phase reveals crater details and highland regions that are often washed out during the full phase.
Why should you care? Because this is the moon showing off its best features! Think of it as the lunar equivalent of perfect golden-hour lighting - all those crater shadows create a stunning three-dimensional effect.
Time: Just after sunset until early morning
Direction: Rising in the eastern sky
Pro Tip: Those shadows along the terminator (the line between light and dark) make for absolutely stunning viewing through even modest binoculars. If you've never done a serious moon-gaze, now's your moment.
Speaking of June 13th, here's a little cosmic perspective for you: On this day in 1983, Pioneer 10 quietly crossed Neptune's orbit, becoming the first human-made object to venture so far. Talk about a cosmic milestone! Launched back in 1972 with a modest 21-month mission plan, this overachiever kept communicating with Earth for over three decades - its last "hello" reaching us in 2003.
Pioneer 10 is still traveling outward today, over 20.5 billion kilometers from Earth. It's just one of five spacecraft (along with Pioneer 11, Voyagers 1 & 2, and New Horizons) on trajectories that will eventually carry them into interstellar space. Our little mechanical emissaries to the stars, wandering eternally among them.
Now this is celestial chemistry at its finest. Mars and Regulus, the brightest star in Leo, will perform an elegant cosmic dance just 0.8 degrees apart - that's less than the width of your pinky finger held at arm's length.
Why should you care? It's a stunning color contrast - Mars with its distinctive rusty-copper glow and Regulus shining brilliant white-blue. The pair creates a visual treat that's both scientifically fascinating and aesthetically gorgeous.
Time: After sunset for several hours
Direction: Western sky in the Leo constellation
If you're willing to sacrifice some sleep, you're in for a real celestial treat as the third-quarter Moon cozies up to ringed Saturn in the pre-dawn sky on the 19th. Their proximity in Aquarius creates one of those "wow" moments that makes even casual skywatchers reach for their phones to snap a picture.
Time: Around 1:30 a.m. local time
Direction: Eastern sky
What you'll see: Third-quarter moon positioned near Saturn
Pro Tip: A telescope will reveal Saturn's rings, which are currently tilted at an angle that offers a spectacular view. Set your alarm - this one's worth the early wake-up call.
Venus is absolutely showing off right now as the "Morning Star," rising about two hours before the sun and outshining literally everything else in the pre-dawn sky. If you're an early riser (or haven't gone to bed yet - I don't judge), you simply can't miss it.
Time: 2-3 hours before sunrise
Direction: Eastern horizon
Pro Tip: Venus is so bright that you can often spot it in twilight before other stars become visible. Use it as your anchor point to orient yourself to the morning sky.
Leo is having quite the moment this week with the Mars-Regulus conjunction. This majestic constellation is one of the few that actually resembles what it's supposed to be—a lion, complete with the distinctive "sickle" forming the lion's mane and head.
Finding Leo is easy: look for the backward question mark (the sickle) with Regulus as the dot at the bottom. The bright triangle of stars to the east forms the lion's hindquarters. And this week, with Mars visiting Regulus, you get an extra beacon guiding you right to it.
While the planets and moon tend to steal the spotlight, this week also offers prime viewing for several magnificent deep-sky objects:
The Milky Way Core: Late night observers get a special treat as our galaxy's center rises, revealing a dense band of stars, dust, and gas that creates one of the most breathtaking sights in astronomy. You'll need dark skies away from city lights, but it's absolutely worth the drive.
M13 Hercules Globular Cluster: High overhead in the evening, this ancient ball of thousands of stars looks like a fuzzy cotton ball to the naked eye, but explodes into a dazzling sphere through even modest telescopes.
Beehive Cluster (M44): This open star cluster in Cancer is visible after sunset and looks spectacular through binoculars.
The universe is putting on quite the performance - all you need to do is look up. And remember, every time you gaze at these celestial wonders, you're participating in the same activity that has captivated humans for thousands of years. There's something profoundly connecting about that, don't you think?

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.

How to see Mars visit a bright star and the moon this June
When you buy through links on our articles, Future and its syndication partners may earn a commission. This has been a most interesting year to follow Mars. If you've been monitoring the Red Planet since the start of 2025, you have no doubt noted the dramatic change in its brightness as well as the occasional interactions it has had with the moon, bright stars and other celestial objects. Mars travels a little more than half of its orbit each Earth year, and thus has oppositions (that point in the sky where it appears directly opposite to the sun in the sky) every two years plus about 50 days (its "synodic period," which is also the longest for any known planet). Prior to 2025, the last opposition of Mars was on Dec. 8, 2022; after 2025, the next will come on Feb. 19, 2027. It reached opposition this year on Jan. 16 and two nights earlier, on Jan. 14, a nearly full moon passed directly in front of Mars as seen from much of North America. Mars is the most Earth-like planet of all known beyond our own, and it passed closest to Earth during the American morning of Jan. 12, just 3.5 days before opposition. But the 2025 apparition of Mars has been one of the poorer and more distant ones in the planet's 15-to-17-year cycle of oppositions near and far. Just three months after opposition, Mars arrived at aphelion (farthest from the sun) in its eccentric orbit, so we came no closer than 59.7 million miles (96.1 million kilometers) to it last winter — some 5.3 light minutes away. Shining with a yellow-orange hue, it attained its peak brightness, gleaming at magnitude -1.3. That's just a trifle fainter than Sirius, the brightest star in the sky. Ever since Jan. 12, however, it has been receding from Earth, and consequently it has gradually been getting dimmer. So, we're leaving it behind, and ever since Feb. 24, Mars has been traveling in prograde (eastward) motion — a long, straight line around the sky, becoming steadily farther away and smaller. Still, in spite of its fade-down, it continued to put on an eye-catching show during February and March with the "twin stars" of Gemini, Pollux and Castor as the brightest member of a prominent, albeit temporary, triangle. And then, on the evening of May 4, Mars made a very close pass near the Beehive Star Cluster (M44), a very pretty sight as viewed through binoculars or a low-power, wide-field telescope. And during the latter part of June, Mars will again make for a couple of eye-catching shows, teaming up first with a bright star and then, late this month, with Earth's nearest neighbor in space. TOP TELESCOPE PICK: Want to see Alcor and the other stars of the Big Dipper? The Celestron NexStar 4SE is ideal for beginners wanting quality, reliable and quick views of celestial objects. For a more in-depth look at our Celestron NexStar 4SE review. Mars now appears as nothing more than a featureless dot in most telescopes. But on Tuesday evening (June 17), it forms a wonderful naked-eye pairing with the thin, only slightly brighter star Regulus in the constellation of Leo the Lion. Observers in the Americas will see the planet and star 2 degrees apart or less from June 13 through June 20, and one degree or less apart June 15 through June 18. For viewers, around 40 degrees north latitude, Regulus and Mars are side by side, only 1.5 degrees apart on June 14, and Mars is 45 arc minutes (three quarters of one degree) almost straight above Regulus on June 17. That will be the evening when they are closest together. Neither one is exceptionally bright; Regulus shines at magnitude +1.34 and Mars is at magnitude +1.41. But the fact that they will appear so near to each other and are so closely matched in brightness will make them appear to stand out in the early evening sky. Look for them around 10 p.m. local daylight time, roughly one-quarter up in the western sky. In addition to their closeness to each other, look for the orange-gold of Mars and blue-white of Regulus to appear intensified by contrast to each other when they are so close together (as seen with the naked eye or binoculars). On Sunday evening, June 29, a waxing crescent moon, 24% illuminated by the sun, will pass very close to Mars and make for a rather attractive sight, low in the western sky at dusk. The moon, moving around Earth in an easterly direction at roughly its own diameter each hour, will appear to pass just below the orange-gold planet. Even though North America will miss out on seeing the moon pass directly in front of Mars (called an "occultation"), Mars will attract attention as it slowly appears to glide above the moon. The view of the moon occulting Mars will be restricted to parts of Ecuador and Peru. After closest approach, the moon will move slowly away from Mars. Locations to the east (or to the right) of a line running roughly from central Texas through central Ontario will be in various stages of twilight at the moment that the moon and planet are closest together (called a "conjunction"). To the west (or to the right) of that line, the sun will be above the horizon when the two are in conjunction, but will still appear relatively close as darkness falls. For places where the two are closest together within an hour or less after sunset, you'll probably initially need binoculars to pick Mars out against the bright twilight sky. Once the sky has sufficiently darkened, however, Mars will be relatively easy to see. For most locations, the upper limb of the moon will skim to within about 20 arc minutes (one-third of a degree) of Mars. For places across the northern U.S. and Canada, the gap between the two will be a bit larger, while across the southern U.S. and the Caribbean, the gap will be a bit smaller. The table below (calculated exclusively for by Joe Rao) provides the specific details for 15 selected cities in the U.S. and Canada. The table gives civil times (all p.m.) of Mars' closest approach to the edge of the moon's upper limb. Separation between Mars and the moon's upper edge is given in terms of minutes of arc (the apparent width of the moon on June 29 is 31 arc minutes), and the percentage of the apparent width of the moon. A value of 0.48, for example, is equal to 48% of the moon's width (or fractionally, slightly less than one-half). Examples: from Miami, closest approach between Mars and the moon is at 10:13 p.m. EDT. Separation is 15 arc minutes or 0.48, which is just under one-half of a moon's width from Mars to the upper edge of the moon. From New York, closest approach is at 9:48 p.m. EDT, the separation is listed at 23 arc minutes or 0.74, which means that 74% of the moon's width will separate Mars from the moon's upper edge.

In the weeks and months that follow, Mars will continue to be a fixture in the evening sky, but will continue to recede from Earth and consequently will get fainter, diminishing to the rank of second magnitude. Passing north of Spica on Sept. 13 and Mercury on Oct. 19, Mars will be getting progressively lower in the sky — more southerly and nearer to the sunset. When it finally fades into the evening twilight glow of early November, it will be on the far side of the sun, some 225 million miles (362 million km) from Earth and just 1/13 as bright as it was in mid-January. It will finally end its run as an evening object when it will be at conjunction with the sun next year, on Jan. 9. Joe Rao serves as an instructor and guest lecturer at New York's Hayden Planetarium. He writes about astronomy for Natural History magazine, Sky and Telescope and other publications.

Are mermaids real and why do bees like purple? The kids' quiz
Melanie, 11, asks: are mermaids real? Yes, there are several species of mermaid in the Pacific Ocean As far as we know, they aren't real – but they have appeared in stories all over the world Yes, they appear only on a full moon They used to be real, but now they only exist on Mars Bobby, 6, asks: why do you laugh when you get tickled? You laugh because it's such a great joke It releases little laughing fairies in your body Tickling triggers a part of your brain that makes you laugh, even if you're not really enjoying it That's your brain's way of saying STOP! Zoe, 6, asks: why do bees like the colour purple? Purple flowers make the best honey To bees, purple looks like the sky Purple flowers have a lot of nectar Bees can only see the colour purple William, 9, asks: what is the biggest star we've discovered? The Sun – the centre of our solar system Sirius, the brightest star in our sky Betelgeuse, the red giant UY Scuti, a giant star Charlie, 7, asks: how long have alligators existed for? About 25 years About 200 years About 200,000 years A long time – more than 150 million years 1:B - As far as we know, mermaids aren't real, but for a few thousand years, people have told stories of half-human, half-fish creatures. It's possible they're based on sea animals such as manatees or dugongs, which might look like mermaids from far off., 2:C - Tickling activates part of your brain called the hypothalamus – the same bit that reacts to surprise or danger. It's thought to be a defence mechanism from our ancestors. That's why you laugh, even if it feels a bit weird or you don't like it., 3:C - Purple flowers often have the most nectar. Bees can't see red, but they have enhanced UV colour receptors, so are drawn to purple and blue flowers., 4:D - UY Scuti is the biggest star we've discovered so far in terms of size. It's a red supergiant star, in the constellation Scutum, around the centre of the Milky Way. It's 1,708 times wider than the Sun!, 5:D - Alligators have existed for more than 150 million years, since when dinosaurs were still around. Dinosaurs became extinct, but alligators survived – scientists aren't sure how. 5 and above. 4 and above. 3 and above. 2 and above. 0 and above. 1 and above.
