A different kind of dark matter could help to resolve an old celestial conundrum.

The surface temperatures and properties of brown dwarfs depend on their precise masses and ages, and range from a few thousand degrees down
to a mere 200 kelvin (comparable to the Earth’s surface temperature) with the warmest group being designated as L Dwarfs, the next warmest
group as T Dwarfs, and the coolest objects as Y Dwarfs. Not surprisingly, because they are so cool, brown dwarfs are faint and hard to detect,
and so although theorists predict that there could be as many brown dwarf stars as there are normal stars our understanding of their evolution
and interior properties is quite incomplete.

NASA's Wide-field Infrared Survey Explorer (WISE), which was sensitive to the emission from cool objects, discovered the Y class of brown dwarfs
in 2011, and today there are twenty-four of them known. CfA astronomer Caroline Morley and her colleagues used the Spitzer Space Telescope and
the Gemini observatory, as well as some other facilities, to refine the distances, luminosities, colors, and spectral characteristics of these
objects and compared the results to current models. The scientists determined the masses and ages for twenty-two of them, and confirmed that,
at least for the slightly warmer Y-dwarfs (whose temperatures are around 450 kelvin) the cloud-free surface models agree with observations.

When a phenomenon moves from “empirical correlation” to “theoretically explained,” that’s one of the biggest deals in science!

On July 10, researchers using NASA’s Stratospheric Observatory for Infrared Astronomy, or SOFIA, will attempt to study
the environment around a distant Kuiper Belt Object, 2014 MU69, which is the next flyby target for NASA’s New Horizons spacecraft.

When New Horizons flies by it, MU69 will be the most distant object ever explored by a spacecraft, over a billion miles farther from our sun
than Pluto. This ancient Kuiper Belt object is not well understood because it is faint, small (likely 12-25-mile (20-40-kilometer across, or
possibly even smaller according to recent ground-based observations), and very far away (approximately 4.1 billion miles from Earth).

In a paper highlighted by Astronomy & Astrophysics journal, a team of researchers from the Instituto de Astrofísica
e Ciências do Espaço (IA3) discovered observational evidence for the existence of two distinct populations of giant planets.

So far, more than 3500 planets have been detected orbiting solar type stars. Although recent results suggest that most planets in our Galaxy are rocky like Earth,
a large population of giant planets, with masses that can go up to 10 or 20 times the mass of Jupiter (itself 320 times the mass of the Earth), was also discovered.

A large amount of the information about how these planets are formed is coming from the analysis of the connection between the planets and their host star. Initial
findings have shown, for example, that there is a tight connection between the metallicity4 of the star and the planet occurrence or frequency. Stellar mass has
also been suggested to influence planet formation efficiency.

Milky Way could have 100 billion brown dwarfs

Our galaxy could have 100 billion brown dwarfs or more, according to work by an international team of astronomers,
led by Koraljka Muzic from the University of Lisbon and Aleks Scholz from the University of St Andrews. On Thursday
6 July Scholz will present their survey of dense star clusters, where brown dwarfs are abundant, at the National
Astronomy Meeting at the University of Hull.
