China launches secretive suborbital vehicle for reusable space transportation system


China conducted a clandestine first test flight of a reusable suborbital vehicle Friday as a part of development of a reusable space transportation system.

The vehicle launched from the Jiuquan Satellite Launch Center Friday and later landed at an airport just over 800 kilometers away at Alxa League in Inner Mongolia Autonomous Region, the China Aerospace Science and Technology Corp. (CASC) announced.

Event Horizon Telescope snaps close-up of supermassive black hole jets

Astronomers have taken a close-up image of a radio jet emitted by a supermassive black hole for the first time. The Event Horizon Telescope (EHT) has zoomed in on this jet with 16 times the resolution and at 10 times higher frequencies than previous observations to learn more about this strange phenomenon.

By name and nature, black holes are pretty much invisible, but they can reveal themselves through the extreme environment they create. As they suck in dust and gas, this material heats up and glows in a disc, creating a bright background on which the silhouette of the black hole can be seen.

The sky is filled with rivers of darkness


Oh, certainly, if you happen to see the Milky Way stretched out above you as well it looks fuzzy, like a stream of milk that gives our galaxy its name (and even gives us the very word galaxy). But that’s an illusion of sorts, the combined light of billions of individual stars too dim to see on their own. Even that just affirms the stellar predominance.

But while your eyes whisper lies, the sky tells the truth: There is more in the heavens above Earth than you have dreamt of. The sky is filled with dust.

Mars InSight reveals first crust-to-core snapshot of Red Planet


NASA’s Mars InSight has provided … well, insight, into the inner workings of the Red Planet. By monitoring “marsquakes” over the past two years the instrument has allowed scientists to measure the thickness and composition of Mars’ crust, mantle and core, revealing some surprises.

While InSight has so far detected 733 marsquakes in its two-year mission, the new studies focused on 35 of those quakes, all registering magnitudes between 3.0 and 4.0. That means they constitute some of the most powerful Mars has to offer – although they might sound pretty minor compared to what Earth is capable of.

NASA's Mars helicopter soars past 1-mile mark in 10th flight over Red Planet


NASA's Mars helicopter Ingenuity has flown its first mile on the Red Planet.

The small chopper surpassed the 1-mile (1.6 km) mark of its total flight distance on Saturday (July 24) when soared over a rocky region called "Raised Ridges" at its Jezero Crater home. The sortie was the 10th and highest trip yet for Ingenuity, which arrived on Mars with NASA's Perseverance rover in February. Ingenuity's first flight occurred in April.

New exotic matter particle, a tetraquark, discovered


Today, the LHCb experiment at CERN is presenting a new discovery at the European Physical Society Conference on High Energy Physics (EPS-HEP). The new particle discovered by LHCb, labeled as Tcc+, is a tetraquark—an exotic hadron containing two quarks and two antiquarks. It is the longest-lived exotic matter particle ever discovered, and the first to contain two heavy quarks and two light antiquarks.
