How to thermally cloak an object
Can you feel the heat? To a thermal camera, which measures infrared radiation, the heat that we can feel is visible, like the heat of a traveler in an airport with a fever or the cold of a leaky window or door in the winter......»»
Complex organic molecules detected in the starless core Lynds 1521E
Using the ARO 12-m telescope, astronomers have investigated a young starless core known as Lynds 1521E (or L1521E). The study resulted in the detection of complex organic molecules in this object. The finding is detailed in a paper April 15 on the ar.....»»

A manifesto for investigating the impacts of object flows on past societies: Objectscapes
World history is often framed in terms of flows of people and migration: humans coming 'out of Africa," the spread of farmers in the Holocene, Phoenician and Greek diasporas over the ancient Mediterranean, the colonization of the world by Europeans f.....»»
Unusual binary system detected with LAMOST
Using the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST), astronomers have discovered an unusual binary system. The newly found binary, designated LAMOST J0140355+392651 (or J0140 for short), consists of a bloated, low-mass proto-.....»»
When stars get too close to each other, they cast out interstellar comets and asteroids
In October 2017, humanity caught its first-ever glimpse of an interstellar object—a visitor from beyond our solar system—passing nearby the sun. We named it "Oumuamua, and its unusual properties fascinated and confounded astronomers. Less than tw.....»»
Self-propelling self-navigating vehicles a step closer
Vehicles that can propel themselves along the water and self-navigate around any object in their path could soon be a reality thanks to new research from The Australian National University (ANU)......»»
Dynamical machine learning accurately reconstructs volume interiors with limited-angle data
Tomographic reconstruction of an object's interior volume from limited angular views is a challenging problem with practical applications in biological imaging, failure analysis of integrated circuits, etc. A team at MIT presents a dynamical machine.....»»
Hubble spots double quasars in merging galaxies
NASA's Hubble Space Telescope is "seeing double." Peering back 10 billion years into the universe's past, Hubble astronomers found a pair of quasars that are so close to each other they look like a single object in ground-based telescopic photos, but.....»»
Search for skyrmion phenomenon finds even stranger magnetic beaded necklace
Physicists on the hunt for a rarely seen magnetic spin texture have discovered another object that bears its hallmarks, hidden in the structure of ultra-thin magnetic films, that they have called an incommensurate spin crystal......»»
NASA analysis: Earth is safe from asteroid Apophis for 100-plus years
The near-Earth object was thought to pose a slight risk of impacting Earth in 2068, but now radar observations have ruled that out......»»
Astronomers image magnetic fields at the edge of M87"s black hole
The Event Horizon Telescope (EHT) collaboration, which produced the first-ever image of a black hole, has today revealed a new view of the massive object at the center of the Messier 87 (M87) galaxy: How it looks in polarized light. This is the first.....»»
B2 1420+32 is a changing-look blazar, study finds
An international team of astronomers has performed multi-wavelength photometric and spectroscopic observations of a blazar known as B2 1420+32. The observational campaign found that the object exhibits a large scale spectral variability and is the so.....»»
Interstellar visitor ‘Oumuamua was a piece of Pluto-like planet, not aliens
In 2017, a cigar-shaped object was spotted in the sky and was identified as coming from outside our solar system. Now researchers think they know what it was......»»

The debate continues: ‘Oumuamua could be remnant of Pluto-like planet
Secret to at least one aspect of object's unusual properties lies in solid nitrogen ice. ASU astrophysicists Steven Desch and Alan P. Jackson set out to explain the odd features of 'Oumuamua and have determined that it is likely a piece of.....»»
Facebook is Making a Bracelet That Lets You Control Computers With Your Brain
Facebook says it has created a wristband that translates motor signals from your brain so you can move a digital object just by thinking about it. From a report: The wristband, which looks like a clunky iPod on a strap, uses sensors to detect movemen.....»»
About 7 interstellar objects pass through the inner solar system every year, study estimates
In October 19th, 2017, the first interstellar object ever detected flew past Earth on its way out of the solar system. Less than two years later, a second object was detected, an easily identified interstellar comet designated as 2I/Borisov. The appe.....»»
Optimal design for acoustic unobservability in water
