Astronomers capture first-ever image of a newborn planet



Astronomers have captured the first ever confirmed image of a newborn planet forming around a young dwarf star – an ambitious task that has previously proved elusive to scientists.

The planet was caught in the act of formation amid a disk of gas and dust surrounding a young dwarf star, known as PDS 70.

The stunning snapshot, considered the first robust detection of a young planet, was captured by the SPHERE instrument on the ESO's’ Very Large Telescope and stands out clearly as a bright point to the right of the blackened center of the image.

The unique photo was made possible thanks to the use of a filter, known as a coronagraph, which blocks the light from the central star and allows the detection of the much fainter disc and planetary companion, the ESO explained.

"These discs around young stars are the birthplaces of planets, but so far only a handful of observations have detected hints of baby planets in them," Miriam Keppler, lead researcher from the Max Planck Institute for Astronomy, said.

The emerging planet is a gas giant with a mass greater than Jupiter, located some 3 billion km from the central star – roughly equivalent to the distance between Uranus and the Sun. 

Data also suggests the planet’s atmosphere is cloudy and has a surface temperature of 1000C, making it much hotter than any planet in our own Solar System.

“After more than a decade of enormous efforts to build this high-tech machine, now SPHERE enables us to reap the harvest with the discovery of baby planets!” Thomas Henning, director at the Max Planck Institute for Astronomy said.

The research has been presented in two papers, which will be published in the journal Astronomy and Astrophysics. 

It builds on previous research from 2015 where a number of newborn planets were observed evolving for the first time.

Scientists hope the detection will offer greater insight into the early stages of planetary evolution and enhance their overall understanding of alien worlds.

Armenian protesters block traffic, railways & airport as protest leader loses PM bid

Anti-government protesters disrupted traffic in Armenia’s capital, blocking railways and roads leading to Yerevan International Airport, after the parliament voted against opposition leader Nikol Pashinyan’s bid for interim PM.
Protesters managed to block streets connecting downtown Yerevan to residential districts, disrupting transportation in Armenia’s capital, footage from the scene shows. 
Yerevan’s metro system has also been paralyzed as demonstrators sit on the tracks, preventing trains from passing.
Meanwhile, protesters disrupted traffic on a road leading to Yerevan’s Zvartnots International Airport, located just 12km from the center of the city. 
Consequently, some passengers had to go the rest of the way on foot in order to catch their flights, according to Sputnik news agency.
Railway services have also been disrupted all across the country amid the demonstrations, a spokesman for South Caucasus Railways confirmed to Interfax. 
Some other highways, including the one connecting th…

Syria threatens to ‘strike Tel Aviv airport’ unless UNSC acts against Israel’s impunity

Damascus has threatened to exercise its legitimate right for self-defense against Israeli aggression and target Tel Aviv airport in a mirror response, unless the Security Council puts an end to IDF intrusions into Syrian airspace.
Apparently fed up with years of Israeli impunity in the Syrian skies and regular strikes carried out in the vicinity of Damascus International Airport, Syria has threatened to retaliate in explicit terms.
“Isn’t time now for the UN Security Council to stop the Israeli repeated aggressions on the Syrian Arab Republic territories?” Syria’s permanent representative to the UN, Dr. Bashar al-Jaafari wondered Tuesday.

Or is it required to draw the attention of the war-makers in this Council by exercising our legitimate right to defend ourself and respond to the Israeli aggression on Damascus International Civil Airport in the same way on Tel Aviv Airport?
Air strikes against alleged ‘Iranian targets’ in close proximity to Syria’s busiest airport have become a norm for…

Iran showcases massive UNDERGROUND missile factory, with new rockets & warheads galore

As Tehran unveiled its newest weapon, it also shared rare footage of a secretive underground complex where Iranian missiles are being built. 
It has vowed to carry on with its missile program, despite objections from the West.
Iran’s new missile was showcased on Thursday, with top military officials unveiling the weapon and, in an unprecedented move, showing the subterranean factory. 
The location of the facility was not disclosed, for obvious reasons.
The facility was described by the Iranian media as an “underground city” – and its scale appears to be quite impressive. Footage from the scene shows vast corridors, full of various missile parts, including warheads, all at different stages of assembly.
The videos also showed workers at the plant fulfilling tasks, from merely spinning nuts to fine-tuning some tiny electronic devices, thought to be parts of the missiles’ guidance system.
The new missile, called Dezful, is said to be an upgraded version of the Zolfaghar ballistic missile. 
It bo…
