New observations from robotic explorers like NASA's Perseverance and Curiosity have revealed much about the ancient past of the Red Planet, where liquid water flowed throughout the planet's surface.
But a deeper, more primary cause for the move from wetness has come to light: Mars was always too small to retain its surface water forever, according to a new study published in the journal Proceedings of the National Academy of Sciences .
Solar system: Amazing reason why planets orbit in same plane explained | HT Tech
Space is one of the most mysterious aspects of nature and one of the most wondrous things is the solar system and the planets in it. A question that often arises is why the sun, and the planets around it, are structured the way they are.
The cloud was so big that it started to collapse and shrink under its own mass. As the spinning cloud of dust and gas started to shrink, it also flattened. At the same time, in the centre of this cloud, all the gas molecules got squeezed together.

Our solar system is well behaved: The set of planets follows near-circular orbits around the sun that don't cross paths or change much.
The gravitational tug-of-war within planetary systems carves out the paths that planets follow as they orbit their respective star. At any instant, these forces of attraction can change these paths by tiny, barely noticeable amounts.
Astronomers See Carbon-Rich Nebulae Where Planets are Forming - Universe Today
Understanding the birth of a planet is a challenging puzzle. We know that planets form inside clouds of gas and dust that surround new stars, known as protoplanetary disks.
The study, nicknamed MAPS , was carried out using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.

WASHINGTON, D.C. — Astronomers have mapped out the chemicals inside of planetary nurseries in extraordinary detail. The newly unveiled maps reveal the locations of dozens of molecules within five protoplanetary disks—regions of dust and gas where planets form around young stars.

The purple ring is the planet's trajectory and the orange rings are the HZ inner and outer boundaries. The planetary system parameters are the same for the same column, but the HZ criteria are different, so the classification may be different.
Exoplanet detection in the past decade by efforts including NASA's Kepler and TESS missions has discovered many worlds that differ substantially from planets in our own Solar System, including more than 150 exoplanets orbiting binary or multi-star systems.
The Harvest Moon of 2021 rises tonight: Here's what to look for | Space
The Harvest Moon rises tonight, accompanied by brightly shining planets Venus and Jupiter. The last full moon before this year's autumnal equinox, the Harvest Moon will be visible during night hours, weather permits, until the early hours of Wednesday.
On the U.S. East Coast, the Harvest Moon will emerge just above the eastern horizon at 7:13 p.m. EDT on the evening of Monday (Sept. 20). It will properly reach its full phase about 40 minutes later, at 7:55 p.m. EDT.
