Humanity has sent robotic missions to every planet in the inner solar system. As one might expect, Mars has been the most frequently visited world in our solar system. There have been a total of 50 missions to Mars, yet more than half of those missions ended in failure.
Although Mars is difficult to launch missions to and land on the surface, the other rocky worlds are even more difficult. Mercury is so close to the sun that any missions are at risk of falling towards the sun, and to date, humanity has not landed a spacecraft on the surface of Mercury.
When stars eat their planets, the carnage can be seen billions of years later
Lithium is the third element on the periodic table . Although most of the atoms formed during the Big Bang were hydrogen and helium, trace amounts of lithium were formed from the Big Bang. About one atom in ten billion so the current model goes.
Astronomers use this effect to distinguish between high-mass brown dwarfs and low-mass stars. If there is plenty of lithium present in the atmosphere, then fusion isn't happening, and it's a brown dwarf. Not much lithium and you have a star. But some stars have atmospheric lithium.
Skywatch: Lots of planets will be visible in our skies | The Mail
The good news is there are LOTS of planets visible at the same time right now, all arranged in a line across the sky like beads on a bracelet.
The bad news is that that time is you're-having-a-laugh o'clock, in the wee small hours of the morning before sunrise...

Sky This Month: August 2022 | Astronomy.com
Midsummer observing means giant planets, with Jupiter and Saturn visible before midnight. Both planets offer hours of amazing views. Saturn is visible all night, while Jupiter rises a bit later. You might catch elusive Mercury in the early evening if you’re lucky.
Mercury modestly hugs the western horizon all month. It’s a favorable apparition for Southern Hemisphere observers but is more challenging for those in the Northern Hemisphere. On Aug.
A Unified Atmospheric Model for Uranus and Neptune - Eos
The ice giants, Uranus and Neptune, are the least understood planets in the solar system. They remain the only worlds that an orbital spacecraft has not visited.
Why these planets appear so different in color despite having very similar physical properties, including vertical temperature profile and atmospheric composition, is a mystery.
Planets Push for Exploration, by Holiday Mathis | Creators Syndicate
The energy release of Mars conjunct Uranus sends many exploring. Travel and sightseeing is one way; social outreach is another; and the world of books and entertainment is a viable option, too. "The real voyage of discovery consists not in seeking new landscapes but in having new eyes.
ARIES (March 21-April 19). You'll blend your skills together to strong effect. Those who know you well have come to expect you to perform at this high level, but fresh eyes will be astounded by all you're able to do in one day.
Super-Earth Ross 508b skims habitable zone of red dwarf
However, red dwarfs are very faint in visible light due to their low surface temperature of less than 4,000 degrees. Previous planet searches using visible light spectrometers have only discovered a few planets around very nearby red dwarfs, such as Proxima Centauri b.
The Astrobiology Center in Japan has successfully developed IRD (InfraRed Doppler instrument), the world's first high-precision infrared spectrograph for 8-meter class telescopes.
Watch Mars and Uranus sidle up in webcast tonight | Space
Mars and Uranus are night-sky neighbors at the moment, and you can get good views of their unusual meetup online tonight (Aug. 1).
The two planets are close enough in the sky right now to be seen together through binoculars or a low-power telescope . But even if you don't have such gear, you can still get good looks at in a webcast tonight.
