Quantum Error Correction Will Enable Quantum Telescopes

Researchers from Australia and Singapore are working on a new quantum technique that could enhance optical VLBI. It’s known as Stimulated Raman Adiabatic Passage (STIRAP), which allows quantum information to be transferred without losses. When imprinted into a quantum error correction code, this technique could allow for VLBI observations into previously inaccessible wavelengths. Once integrated …

Space Based Starshades Will Make Large Ground Telescopes the Most Powerful Exoplanet Finders

Hybrid observatories will combine a 100 meter diameter starshade in space with a telescope on the ground. The Hybrid Observatory for Earth-like Exoplanets (HOEE) would convert the largest ground-based telescopes now under construction (Giant Magellan Telescope, Thirty Meter Telescope, and Extremely Large Telescope) into the most powerful planet finders yet designed. No other proposed equipment …

Proposed First Gravity Lens Mission by 2028 that Could Spot Large Islands on Exoplanets by 2050

A meter-class telescope with a coronagraph to block solar light, placed in the strong interference region of the solar gravitational lens (SGL), is capable of imaging an exoplanet at a distance of up to 30 parsecs with a few 10 km-scale resolution on its surface. The picture shows results of a simulation of the effects …

Millions of Telescopes 4 Light Days From Earth Could Permanently Explore Other Solar Systems

If we send telescopes out to 4 light days we can use the gravity of the sun to amplify the power of telescopes by 100 billion times. Although we can build larger telescopes with higher resolution than exists today near to Earth, the telescopes that are sent out to gravitational lensing regions would resolve much …

Feasible and Affordable Missions for Exoplanet Imaging

The solar gravitational lens (SGL) is characterized by remarkable properties: it offers brightness amplification of up to a factor of ~1e11 [100 billion amplification] (at 1 um) and extreme angular resolution (~1e-10 arcsec). As such, it allows for extraordinary observational capabilities for direct high-resolution imaging and spectroscopy of Earth-like exoplanets. Above – Artist’s depiction of …

Carnival of Space 637 – Smallest Confirmed Dwarf Planet Might Mean Over 100 in Our Solar System

The Carnival of Space 637 is up at Universe Today. Universe Today – Asteroid Hygiea is Round Enough That it Could Qualify as a Dwarf Planet, the Smallest in the Solar System. Within the Main Asteroid Belt, there are a number of larger bodies that have defied traditional classification. The largest among them is Ceres, …

Improved Telescope to Directly Image Alpha Centauri Exoplanets and Other Exoplanet Updates

1. Newly-built planet-finding instrument installed on Very Large Telescope aims to be first to directly image a habitable exoplanet. The instrument, called NEAR (Near Earths in the AlphaCen Region), is designed to hunt for exoplanets in our neighbouring star system, Alpha Centauri, within the “habitable zones” of its two Sun-like stars, where water could potentially …

Three Radio Telescopes will be Added to the Black Hole Imaging Array

Eight radio telescopes were used to image a black hole. They were ALMA, APEX, the IRAM 30-meter telescope, the James Clerk Maxwell Telescope, the Large Millimeter Telescope Alfonso Serrano, the Submillimeter Array, the Submillimeter Telescope, and the South Pole Telescope. Three more radio telescopes will be added to the Event Horizon Telescope project (EHT) over …

Event Horizon Array of Eight Radio Telescope Shows First Blackhole Image

The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and …
