Formalhaut A with First Asteroid Belt Seen Outside Solar System
Fomalhaut A is a bright star and was known to the Persian and Arabic Astronomers. The name of the star is Arabic and means “mouth of the fish”. It belongs to a Tripple Star System 25 light-years away from earth. Formalhaut A has several notable characteristics: Fomalhaut Dusty Debris Disk (MIRI Image), James Webb Telescope…

HL Tau Protoplanetary Disk Contains More Water Than Earth
The observations show that there is at least three times more water in the inner disc of the young Sun-like star HL Tauri than in all of Earth’s oceans combined. HL Tau also called HL Tauri is a young T Tauri star located approximately 450 light-years away from earth in the Taurus Molecular Cloud. It…

Young Star HH 211 with Bipolar Jets is a Source of Molecular Emission
HH 211 is a young bipolar protostellar outflow that provides insights into the early stages of star formation. Here are the key points about HH 211 from the search results: Molecular Emission HH 211 is a prominent source of molecular emission, particularly molecular hydrogen (H2), which traces the outflow’s shocked molecular gas. The molecular emission dominates…

Very-Low-Mass Star ISO-Chal 147 with Abundant Hydrocarbons in Protoplanetary Disk
ISO-Chal-1471 is a young, low-mass star located approximately 600 light-years away from Earth. ISO-Chal 147 is located in the Chamaeleon I star-forming cloud. It is a red dwarf star, which is a type of star that is very common in the Milky Way and burns through fuel slowly. Here are the key points from recent…

Dracula’s Chivito (IRAS 23077+6707) Largest Known Protoplanetary Disk with Carbon-Based Molecules
Dracula’s Chivito, also known as IRAS 23077+6707, is the largest known disk of its kind. It was discovered during a study of active galactic nucleus candidates using images from the Pan-STARRS research project. This edge-on disk completely obscures its central star and is associated with an infrared light source in the same region of the sky.…

Star TW Hydrae with Protoplanetary Disc
TW Hydrae is a young T Tauri star located about 196 light-years away in the constellation Hydra. It is surrounded by a protoplanetary disk. Protoplanetary Disk Chemical Composition The TW Hydrae disk provides a detailed look at the chemical environment where planets are forming, with clear evidence of snow lines, dust evolution, and volatile depletion…

Circumstellar Disk Around Star PDS 70
PDS 70 is a young T Tauri star located about 370 light-years away in the constellation Centaurus. It is surrounded by a protoplanetary disk with a large gap extending from around 65 to 140 AU. Image also shows the PDS 70 cexoplanets. Planetary System Protoplanetary Disk The PDS 70 system provides a rare opportunity to…

What Einstein, Newton and Kepler Did not Know About the Solar System During Their Lifetime
Kepler When Kepler established the first theory and three principles of our solar system he could describe the movement of the planets around the sun but he could not explain why these planets would not vanish in the void around the solar system. He assumed magnetic fields to be the tether to hold our planets…

Einstein’s Glitch in Gravity
https://iopscience.iop.org/article/10.1088/1475-7516/2024/03/045 Robin Y. Wen1,2, Lukas T. Hergt3, Niayesh Afshordi4,5,6 and Douglas Scott3 Gravity on large scales is weaker by roughly 1 Percent. Citation: “Additionally, we find that roughly one percent weaker superhorizon gravity can somewhat ease the Hubble and clustering tensions in a range of cosmological observations, although at the expense of spoiling fits to the baryonic acoustic oscillation…
