Climates Of Temperate Rocky Planets With He-dominated Atmospheres
3+ hour, 56+ min ago (162+ words) [astro-ph.EP] We present radiative-convective modeling of rocky exoplanets with He-dominated atmospheres and low envelope mass fractions. Helium has a steeper adiabatic temperature profile than N2 and H2 as it has fewer degrees of freedom. Line broadening differences are small, collision-induced absorption…...
Earth may escape the Sun, but life still has an expiry date, scientists say
53+ min ago (443+ words) Moneycontrol.com Earth may escape the Sun, but life still has an expiry date, scientists say Earth may not be destroyed by the Sun after all, according to a new astronomical study that challenges a long-held prediction. Researchers say the…...
A red dwarf star called TRAPPIST-1, just 40 light-years from Earth, hosts seven Earth-sized planets — including three orbiting in the narrow zone where liquid water could potentially survive
1+ hour, 40+ min ago (30+ words) TRAPPIST-1 is not impressive by the usual standards of stargazing. It is too faint to see with the naked eye, far cooler and smaller than the Sun, and located...
NASA maps the magnetic heart of a cosmic 'Lighthouse"
2+ hour, 47+ min ago (415+ words) For nearly two decades, astronomers have suspected that the Lighthouse Nebula, an elegant, needle-thin structure stretching across space, was sculpted by particles escaping from a pulsar and flowing along the galaxy’s magnetic field lines. Now, thanks to NASA’s Imaging X-ray…...
Venus turns so slowly that a single day there lasts longer than its entire year, and it spins backwards, so from its surface the Sun would rise in the west.
3+ hour, 40+ min ago (940+ words) The simplest way to make Venus feel strange is not to begin with its heat, its pressure, or its acid clouds. It is to begin with a clock....
LEGO presented a detailed constructor of the Hubble Space Telescope
5+ hour, 23+ min ago (262+ words) The Hubble Space Telescope, which has been in orbit since 1990, has revolutionized astronomy. To pay tribute to this iconic device, the LEGO company has announced a large-scale constructor for fans of space and technology. This is already the second attempt…...
NASA rover takes a closer look at organic carbon on Mars
7+ hour, 40+ min ago (707+ words) Using NASA’s Perseverance rover, scientists are getting a greater understanding of the nature of some of the organic carbon — the molecular backbone for all known living organisms — detected on Mars as they explore the question of whether Earth’s planetary neighbor…...
Mars produces the largest dust storms in the solar system, and every few years one can swell until it wraps the entire planet in haze for weeks, which is what finally killed NASA's Opportunity rover in 2018.
7+ hour, 40+ min ago (653+ words) Mars looks still from a telescope, a rust-red disk hanging in the sky with no oceans, no forests and no weather systems large enough for the eye to follow....
Exp Uns R2egym 33 6x Glm 4 7 Traces Jupiter Cleaned — AI Model

Limited routing data available for Exp Uns R2egym 33 6x Glm 4 7 Traces Jupiter Cleaned. Intelligence insights will appear as more requests are…...
The star and the cosmic feast: betrayed by an excess of lithium, it devours its own planets
4+ hour, 19+ min ago (512+ words) It seems, however, that this has merely been an appetiser for our star, and that the main course is due to arrive shortly: a brown dwarf located nearby. ‘Shortly’ in astronomical terms, that is. That’s quite a mouthful, because a…...
