Carnival of Space #617

Carnival of Space #617 Welcome to the 617th Carnival of Space! The Carnival is a community of space science and astronomy writers and bloggers, who submit their best work each week for your benefit. We have a fantastic roundup today so now, on to this week’s worth of stories! Universe Today: Martian Clouds Might Start […]

Tidal tails detected around dwarf galaxy DDO 44

Tidal tails detected around dwarf galaxy DDO 44 By conducting deep, wide-area imaging survey of the galaxy NGC 2403 and its environment, including the dwarf satellite galaxy DDO 44, astronomers have detected tidal tails emanating from the dwarf. The finding, presented in a paper published June 19, could shed more light on the interactions between […]

Scientist develops novel algorithm to aid search for exoplanets

Scientist develops novel algorithm to aid search for exoplanets Inspired by movie streaming services such as Netflix or Hulu, a Southwest Research Institute scientist developed a technique to look for stars likely to host giant, Jupiter-sized planets outside of our solar system. She developed an algorithm to identify stars likely to host giant exoplanets, based […]

MUSE reveals a glowing ring of light in the distant universe

MUSE reveals a glowing ring of light in the distant universe The MUSE instrument on ESO’s Very Large Telescope in Chile has revealed very detailed halos of neutral hydrogen around distant galaxies. A new result zooms on a few such halos, one of them forming a large, almost-complete ring of light. This result will be […]

Study shows how icy outer solar system satellites may have formed

Study shows how icy outer solar system satellites may have formed Using sophisticated computer simulations and observations, a team led by researchers from the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology has shown how the so-called trans-Neptunian objects (or TNOs) may have formed. TNOs, which include the dwarf planet Pluto, are a group […]

Uranus’ Rings are Surprisingly Bright in Thermal Emissions

Uranus’ Rings are Surprisingly Bright in Thermal Emissions New observations by ALMA and the VLT provide the most-detailed look yet at Uranus’ system of rings, revealing things about their temperature and particle distribution The post Uranus’ Rings are Surprisingly Bright in Thermal Emissions appeared first on Universe Today.

Messier 88 – the NGC 4501 Spiral Galaxy Located in the Coma Berenices constellation, about 50 to 60 million light-years from Earth, is the spiral galaxy known as Messier 88 The post Messier 88 – the NGC 4501 Spiral Galaxy appeared first on Universe Today. Universe Today Go to Source

Galaxy clusters caught in a first kiss

Galaxy clusters caught in a first kiss For the first time, astronomers have found two giant clusters of galaxies that are just about to collide. This observation can be seen as a missing ‘piece of the puzzle’ in our understanding of the formation of structure in the universe, since large-scale structures—such as galaxies and clusters […]

Smash and grab: A heavyweight stellar champion for dying stars

Smash and grab: A heavyweight stellar champion for dying stars Dying stars that cast off their outer envelopes to form the beautiful yet enigmatic “planetary nebulae” (PNe) have a new heavy-weight champion, the innocuously named PNe BMP1613-5406. Massive stars live fast and die young, exploding as powerful supernovae after only a few million years. However, […]

Model suggests how early dark energy could resolve the Hubble tension

Model suggests how early dark energy could resolve the Hubble tension The universe is continuously expanding, yet the exact rate at which it does so remains unclear, and has so far only been approximated using NASA’s Hubble Space Telescope and other similar instruments. Moreover, in recent years, astronomers using the Hubble telescope have unveiled a […]

Astronomers detect 130 short period variable stars

Astronomers detect 130 short period variable stars By conducting photometric observations of the open cluster Stock 8 and its surrounding region, astronomers have identified 130 short-period variable stars, classifying 51 of them as members of the cluster. A paper detailing the findings appeared June 18 on the arXiv pre-print repository. phys.org Go to Source

Subaru Telescope identifies the outermost edge of the Milky Way system

Subaru Telescope identifies the outermost edge of the Milky Way system A team of researchers identified the outermost edge of the Milky Way galaxy. Using the Subaru Telescope, the researchers examined the boundary of the stellar system that makes up the galaxy. The ultimate size of the galaxy is 520,000 light years in radius, 20 […]
