A photographer recently snapped images of vibrant green streaks of light hanging apparently motionless in the star-filled sky above a U.S. mountain range. The eerie light show may look like auroras, but it’s actually an even rarer phenomenon.

Aaron Watson captured the stunning display near the West Elk Mountains in Colorado. The streaky emerald lights emerged just before midnight on June 21 and lasted for around 2 hours, during which they slowly shifted across the sky, Watson told Live Science in an email. Similar but less-intense versions of these lights were also spotted in other parts of Colorado, according to Spaceweather.com.

At first, Watson believed the lights belonged to noctilucent, or night shining, clouds, which were forecast to become more frequent in June and July this year. But as the vibrant colors emerged, this seemed unlikely. He also speculated they could be a slow-moving auroral display or a related phenomena, such as STEVE or a stable auroral arc that was set off by a solar storm bashing into Earth.

However, there was no solar storm at this time. Instead, the lights are the result of a phenomenon known as “airglow,” which is triggered in the upper reaches of Earth’s atmosphere by less-extreme forms of solar radiation. Airglow is rarely seen from the ground, but it could become a more common sight in the coming months and years as solar activity ramps up, Spaceweather.com said.

Experts recently revealed to Live Science that the upcoming peak of solar activity, which was due to arrive in 2025 and be relatively weak compared with historic past peaks, may actually arrive as early as the end of 2023 and be more active than previously expected. The sight of such vibrant airglow further supports this hypothesis. 

A study published March 2021 in the journal  JGR Space Physics, revealed that airglow has historically been most visible during previous solar maximums — the period of the roughly 11-year solar cycle where solar activity peaks and the sun releases more radiation and solar storms. Tracking changes in airglow can therefore help track solar cycle progression, according to NASA. (Auroras also become more common during the solar maximum.)

Airglow and auroras are both triggered by solar radiation hitting Earth, but the mechanisms behind them are very different: Auroras form when powerful streams of solar radiation, known as solar wind, or fast-moving clouds of magnetized plasma, known as coronal mass ejections (CMEs), smash into Earth’s magnetic field. This temporarily weakens Earth’s defensive shield, enabling solar radiation to penetrate deep into the atmosphere and excite air molecules so they emit bright, dancing colors.  Image 1 of 2The green color of this airglow is caused by excited oxygen atoms.

But airglow is created by gradual solar radiation, which ionizes, or strips electrons from, gas molecules during the day. At night, these ionized molecules react with gases carrying an extra electron to regain their lost particles. These reactions release a lot of energy, which is given off as light similar to those emitted by auroras. But it causes a more gradual and often fainter light show.  related stories—Ethereal ‘halo’ and light arcs around the sun captured in photos of ultra-rare phenomena

Airglow forms 50 to 300 miles (80 to 480 kilometers) above Earth’s surface in a region of the atmosphere known as the ionosphere. At higher altitudes, airglow takes on a red color, which is produced by excited nitrogen atoms. But the green lights in the new image are a result of excited oxygen atoms and are most prominent between 56 and 62 miles (90 and 100 km) above the ground, according to Spaceweather.com.

Airglow is not the only sign from the upper atmosphere that solar maximum is fast approaching. The thermosphere, the second last layer of the atmosphere that overlaps with the ionosphere, is also warming faster than it has in almost 20 years as it soaks up energy from increasingly frequent solar storms.

Terror charge against Kneecap rapper cannot continue, court says

Terror charge against Kneecap rapper cannot continue, court says

A terror charge against Kneecap rapper Liam Og O hAnnaidh has been thrown out by a court.

The Irish rapper, who performs under the name Mo Chara, appeared at Woolwich Crown Court on a single terror charge.

Giving his ruling, chief magistrate Paul Goldspring said: “These proceedings against the defendant were instituted unlawfully and are null.”

The 27-year-old had been accused of displaying a flag in support of Hezbollah at a gig at the O2 Forum in Kentish Town, north London, on 21 November last year.

He had been on unconditional bail since his first court appearance in June.

After delivering his ruling, the judge said: “Mr O hAnnaidh, you are free to go,” which was met by cheers in the public gallery and applause.

The levity was met with a stern reprimand, with the judge adding: “You can do your celebrating outside, but the court now has other business to attend to”.

Both of O hAnnaidh’s parents were in court to support him.

‘We’re right and you’re wrong’

O hAnnaidh: ‘We’re right and you’re wrong’

Speaking outside court, O hAnnaidh thanked his legal team and interpreter, before addressing his large crowd of supporters.

He said: “This entire process was never about me, never about any threat to the public, never about terrorism. A word used by your government to discredit people you oppress. It was always about Gaza. About what happens if you dare to speak up.

“As people from Ireland, we know oppression, colonialism, famine and genocide. We have suffered and still suffer under your empire.

“Your attempts to silence us have failed, because we’re right and you’re wrong… We will not be silent. We said we’d fight you in your court and we would win, and today we have.

If anyone on this planet is guilty of terrorism, it’s the British state. Free Palestine. Tiocfaidh ar la [Irish for our day will come].”

The audience responded with cheers and chants of “Free, free Palestine”.

Judge says prosecution’s earlier arguments ‘defy logic’

At the start of the hearing, O hAnnaidh stood to confirm his name, date of birth and current address, speaking in Irish with his words translated by an interpreter. The judge then summarised his judgement for the court.

He made clear the purpose of the hearing was not to determine O hAnnaidh’s innocence or guilt, but about whether the court had jurisdiction to hear the case.

He went on to say he agreed with O hAnnaidh’s lawyers, who argued that the Attorney General had not given permission for the case to be brought against the defendant when police informed him he was to face a terror charge on 21 May.

Criminal proceedings are instituted when a criminal charge is first issued, not when the defendant first appears in court.

Concluding the reasons for his decision, the chief magistrate said: “I find that these proceedings were not instituted in the correct form, lacking the necessary DPP (Director of Public Prosecutions) and AG (Attorney General) consent within the six-month statutory time limit.

“The time limit requires consent to have been granted at the time or before the issue of the requisition.

“Consequently, the charge is unlawful and null and this court has no jurisdiction to try the charge.”

Sweeping aside the prosecution’s previous argument that permission from the DPP and AG was not required until the defendant’s first court appearance, and that permission did not need to be sought in order to bring a criminal charge, the chief magistrate said such arguments “defy logic”.

Following the hearing, a Metropolitan Police spokesperson said: “We will work with the Crown Prosecution Service to understand the potential implications of this ruling for us and how that might impact on the processing of such cases in the future.”

Kneecap‘s manager Daniel Lambert said the rap trio were on the “right side of history”, and said in a post on X: “We said we would fight them and win. We did (Twice). Kneecap has NO charges OR convictions in ANY country, EVER.”

Last year, Kneecap won a discrimination case against the UK government after Conservative leader Kemi Badenoch tried to refuse them a £14,250 funding award when she was business secretary.

Irish First Minister: ‘Kneecap used their platform to expose genocide’

Swiftly responding to the court ruling, Northern Ireland’s First Minister Michelle O’Neill said on social media that she welcomed the decision, saying: “These charges were part of a calculated attempt to silence those who stand up and speak out against the Israeli genocide in Gaza.

“Kneecap have used their platform on stages across the world to expose this genocide, and it is the responsibility of all of us to continue speaking out and standing against injustice in Palestine.”

Sinn Fein leader Mary Lou McDonald wrote on X: “Mo Chara spoke out against Israel’s genocide, for the people of Gaza, for a free Palestine.

“The charges were an attempt to shut him up, to silence protest. It failed. He’s free. Kneecap are not the story. Genocide is the story.”

The venue of the hearing had been changed at short notice, following a burst mains pipe at Westminster Magistrates’ Court.

Bob Vylan: BBC partly upholds complaints over Glastonbury set

Bob Vylan: BBC partly upholds complaints over Glastonbury set

Bob Vylan’s Glastonbury Festival set breached BBC editorial standards when it was livestreamed, its Executive Complaints Unit (ECU) has found.

During their performance at Worthy Farm in June, the punk-rap duo led the crowd in chants of “death to the IDF”.

The ECU received four complaints about the performance relating to incitement to violence, terrorism or ethnic cleansing, hate speech and expressions of antisemitism.

Its ruling, which was published on Thursday, was largely made based on frontman Bobby Vylan’s chants, as well as reciting the slogans, “From the river to the sea” and “Free, free Palestine”.

The ruling also referenced when the same group member described the boss of a record company “in the most abusive terms” and referred to “f****** Zionists” – as it breached the guidelines of harm and offence that describe using “unduly intimidating, humiliating, intrusive, aggressive or derogatory remarks aimed at real people”.

But while the investigation found that harm and offence standards had been overstepped, the corporation was cleared of breaching its guidelines relating to material that is likely to encourage or incite crime.

The ECU said: “In the context of a performance at a music festival, the chanting of slogans can be regarded as primarily an invitation to endorse a particular attitude.

“References to ‘Free Palestine’ and ‘From the river to the sea’, while viewed by some as implying the disappearance of the state of Israel, can also be regarded as no more than expressions of support for aspirations to a Palestinian state and do not of themselves threaten violent action.

“‘Death, death to the IDF’ is clearly more problematic, but it is directed at an institution rather than individuals, and one which is not defined by ethnic or religious composition.”

It further characterised the comments made about the record boss as “antisemitic”.

The ECU said: “Although Bob Vylan referred to ‘Zionists’ rather than ‘Jews’, that appeared to the ECU to be a distinction with very little difference in this instance.

“The ECU therefore shares the view that the content of this act, taken in the round, can fairly be characterised as antisemitic.”

The ruling cleared the BBC of breaching its standards of impartiality, stating that the coverage of the festival is not in line with coverage of news and current affairs.

The ECU said: “While there may be festivals the BBC would not cover on account of their polemical character, a wide tolerance for expressions of opinion by performers or audiences would be in keeping with audience expectations for events it does cover.

“While recognising there is widespread disagreement with the political views expressed by Bob Vylan on this occasion, the ECU did not consider they represented a breach of the BBC’s standards of impartiality in this context.”

Following the performance the corporation issued an apology to viewers, especially the Jewish community, and promised to take action to “ensure proper accountability”.

In July, the BBC said they would no longer live broadcast “high risk” performances.

The corporation also suggested disciplinary action could be taken against staff who failed to halt the livestream.

Avon and Somerset Police also launched an investigation into the band’s Glastonbury comments.

Earlier this month, the band had a Dutch gig cancelled after their frontman made controversial comments over the death of right-wing political activist Charlie Kirk.
