Planets made of dark matter may have blown up | Space

Dark matter remains frustratingly elusive. We have not seen any direct detection in any of our laboratory experiments, and at cosmic scales we only have circumstantial evidence that it exists. 

Now, a new hypothesis proposes that a large fraction of dark matter may be bound up inside tight balls the size of Neptune — so-called dark matter planets.

Amazing! There are 2 other Jupiter sized planets; they will shock you | Tech News

"The discovery of the two new planets was made in the wake of precise searches, using methods of artificial intelligence," said co-author Shay Zucker, head of Tel Aviv University's Porter School of the Environment and Earth Sciences, in a statement .

These planets are simply shocking, the state that they are in. As per the official information, the two new planets are referred to as "Hot Jupiters" due to their size and proximity to their host star.

MIRECLE: Science Yield for a Mid-IR Explorer-Class Mission To Study Non-Transiting Rocky Planets ...

Emission spectroscopy metric (ESM) from Kempton et al. (2018) for all known planets with M sin i less than 6 ME. Top: ESM as traditionally defined at 7.5 µm. Bottom: Same metric but defined at 15 µm. Transiting planets are marked in orange.

Recent investigations have demonstrated the potential for utilizing a new observational and data analysis technique for studying the atmospheres of non-transiting exoplanets with combined light that relies on acquiring simultaneous, broad-wavelength spectra and resolving planetary infrared ...

Dwarf planet Ceres powers its geologic activity using radioactive materials below its crust

Dwarf planet Ceres is abuzz with geologic activity.

Humanity didn’t get any good views of the surface of Ceres until 2015, when NASA’s Dawn mission snapped the first (relatively) close-by images of the dwarf planet.

Among the structures, Dawn captured was a large plateau on one side of Ceres similar in size and nature to the continents of Earth, localized series of fractures in its curst, and mineral deposits that hinted at an ancient, evaporated ocean.

Super-Earth skimming habitable zone of red dwarf -- ScienceDaily

In the infrared wavelengths red dwarfs are brighter. So the Astrobiology Center in Japan developed an infrared observational instrument mounted on the Subaru Telescope to search for signs of planets around red dwarf stars.

The first fruits of this search are signs of a super-Earth four times the mass of the Earth circling the star Ross 508, located 37 light-years away in the constellation Serpens.

Investment from UT Austin, Other Partners Accelerates Construction of Giant Magellan Telescope - ...

AUSTIN, Texas — The Giant Magellan Telescope (GMT) is a next-generation optical/infrared telescope being developed in northern Chile that will yield important discoveries on topics such as galaxies in the early universe and Earth-sized planets orbiting nearby stars.

The University of Texas at Austin is investing an additional $45 million in the GMT, the world's most powerful telescope. This additional funding brings the university's total commitment to $110.3 million.
