Rubin observatory will be a new step in accessing far reaches of space
An exciting new step in access to the far reaches of space and time increasingly will become available when the new Vera C. Rubin Observatory comes into full operation ('Providing a detailed look at the cosmos,' June 25). Funded by the National Science Foundation and the US Department of Energy's Office of Science, and located on an Andean mountain in Chile, its unprecedented telescopic and camera capacity will secure data and imagery essential to further knowledge of the dark energy and dark matter composing most of the universe. In my opinion, telescopic exploring of the cosmos, along with extraterrestrial probes and telescopes, deserve top priority over anything like a plan to colonize Mars. Cannot far-flung telescopes, robotic craft and AI be combined to obviate the need for human presence requiring a transported environment? Would that not be a better investment of resources? Putting humans on Mars would be a new place for old problems.

How to see the letters X and V on the moon tonight
The full moon is a glorious sight, and the sliver of a brand-new moon a wispy delight, but tonight's first-quarter moon has its own unique treat — for a few hours, you can make out the letters X and V on the lunar surface. Here's how. As the photo shows, the lunar X appears about a third of the way from the bottom of the moon, while the Lunar V is a little above the centre. Both features straddle the line between the light and dark sides of the moon, known as the terminator, with the X appearing a little into the dark side, and the V closer to the light side. They're not really there on the surface, and you can't see them at any other time. What you're looking at is called the 'clair-obscur' effect, in which the play of light and shadow on the surface creates the appearance of shapes; in this case, giant letters, formed by the partially lit edges of craters. According to British astronomer Mary McIntyre, the effect kicks off tonight at about 7:30 p.m. ET, and should last about four hours. That means by the time the sun has set and the moon is at its brightest, you should be able to get a good look, clouds permitting. Naked eye is a little tricky, since they are quite small. But decent binoculars (or better yet a small telescope) should bring them into focus. Humans have been looking at the moon since we were human, and through telescopes since they were invented, so it's not surprising that other transient shapes have been noticed and given evocative names, including the jewelled handle, Cassini's moon maiden, Plato's hook and the eyes of Clavius, not to mention the so-called 'man in the moon' that many people see in the full moon. McIntyre has a chart of when to look for them, while BBC's Sky at Night Magazine has a nice picture that shows their locations. The best part about all this is that if you miss them, they'll come back again every 28 days, forever.

Scientists spot potential ‘interstellar object' in our solar system
Scientists have identified a new object that may have originated outside our solar system. If confirmed, this would be only the third instance of an interstellar object ever spotted. The object has been temporarily named A11pl3Z and is being tracked by telescopes worldwide. The two previously confirmed interstellar visitors were ʻOumuamua in 2017 and 2I/Borisov in 2019. Researchers anticipate discovering more such objects in the future with the help of new, powerful telescopes.

Space photo of the day for June 17, 2025
When you buy through links on our articles, Future and its syndication partners may earn a commission. Big telescopes feature some of the finest and most precise mirrors in the world. So when one gets dirty, what happens? The European Southern Observatory (ESO) operates some of the most powerful telescopes in the world. Established in 1962 by 16 countries across the globe, the ESO is a hub for astronomers looking to uncover the mysteries of our universe. The observatory hosts four extremely powerful telescopes, which are used to survey the farthest corners of our galaxy, studying a variety of space structures and phenomena, from black holes to stars to asteroids. While ESO's headquarters are in Garching, Germany, its four telescopes all sit in the Atacama Desert in Chile (hence the "Southern" part of ESO name). This photo was taken at the La Silla Observatory in Chile. ESO hosts four different telescopes in Chile: the Very Large Telescope (VLT), the Atacama Large Millimeter/submillimeter Array (ALMA), the Extremely Large Telescope (ELT, which is currently being built), and La Silla, the subject of this photo. While all four facilities focus on solving the mysteries of space, La Silla is centered specifically on finding exoplanets. Its two telescopes, the 11.5-foot (3.5 meters) New Technology Telescope (NTT) and the 11.8-foot (3.6 m) telescope both use ultraprecise mirrors to bounce images back from space for analysis. In this photo, staff at La Silla work to clean the 11.8-foot telescope's primary mirror. As the mirror was made with fused silica, it takes a delicate process to restore it to a clean, ultraprecise state. Staff have to chemically strip the mirror's old aluminum coating before rinsing it with demineralized water. The mirror then goes into a special vacuum chamber, where aluminum is deposited in a new layer thinner than the width of a human hair. If the aluminum layer were too thick or uneven, the mirror would lose its precision and with it, data from space. You can read more about ESO's many telescopes and their work looking at exoplanets and other structures within our universe.
