Researchers: There Are Cold Planets Throughout Our Galaxy | Mind Matters

Researchers from Osaka University, using gravitational microlensing, have determined that there are cold planets throughout our galaxy. Cold planets would have average temperatures below the freezing point.

The results show that the planetary distribution is not strongly dependent on the distance from the Galactic center. Instead, cold planets orbiting far from their stars seem to exist universally in the Milky Way.

Astronauts' bodily fluids might help build concrete-type shelters on other planets - The

Given the expense and difficulty of getting building materials to places like the moon or Mars, the idea of construction is tricky at best.

A new study suggests some surprising materials that could make the task much easier: astronauts' blood, urine, or even tears.

Sun-Like Stars Devour Planets in Chaotic Regions of Space

Astronomers have discovered that as many as a quarter of stars like the Sun eventually consume their own planets, in findings which suggest that they have a chaotic and destructive history.

The international team led by Lorenzo Spina, a postdoctoral research fellow at the Italian National Institute for Astrophysics, found hints that such a process might be occurring by studying exoplanet systems where the orbit of one planet seemed to be disturbing the other.

Planets form in organic soups with different ingredients: A series of new images reveals that

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.

A series of 20 papers detailing the project, appropriately named Molecules with ALMA at Planet-forming Scales, or MAPS, was published today in the open-access repository arXiv.

The moon will visit Saturn and Jupiter this week in skywatching doubleheader | Space

It's an excellent week to go skywatching as the moon creeps up to the two largest planets in our solar system .

On Thursday (Sept. 16), it will be the turn of what many consider to be the most beautiful of all telescopic objects, the ringed planet Saturn . The following night, the colossus of the solar system, mighty Jupiter , will take the spotlight.

Comparison of Host Stars with Solar System Planets – Exoplanet Exploration: Planets Beyond our

This slide shows the difference in temperature between planets orbiting an M Dwarf star and our Sun. The second view shows their relative distance from their star.

Key point: Exoplanets orbit in the vicinity of the host star, so they are generally much hotter than planets in the solar system.
