A fridge-size asteroid skimmed Earth this week in the third-closest fly-by ever

This one used the sun to hide until it was right over us.

A sneaky space rock sped by Antarctica on Sunday without any advance warning and narrowly avoided being fully incinerated by Earth’s atmosphere.

Asteroid 2021 UA1 goes down as the third-closest fly-by of our planet by a near-Earth object that didn’t end in an impact. The cosmic boulder is estimated to be about two meters (6.6 feet) in diameter, the size of a large appliance or a golf cart. Had it actually hit our planet, the vast majority of it would almost certainly have burned up in the atmosphere.

For comparison, the bolide that exploded over Russia in 2013, blowing out thousands of windows in the city of Chelyabinsk, was probably at least 20 times bigger, and only a small boulder survived to impact the surface in that instance.

Instead, 2021 UA1 passed over Antarctica on Sunday evening Pacific time at an altitude of about 1,800 miles (3,000 kilometers). That’s higher than where the International Space Station orbits but significantly closer than the ring of large communications satellites in geostationary orbit. Asteroid 2020 QG passed just a little bit closer in August 2020, but the closest approach ever recorded in which the asteroid escaped unscathed came last November when 2020 VT4 flew overhead at nearly the same altitude as the ISS (around 250 miles or 400 kilometers up).

2021 UA approached us from the direction of the sun — just like the Chelyabinsk bolide, which was undetected before impact — making it impossible for astronomers to spot ahead of time. Upcoming missions like NASA’s NEO Surveyor are designed to eliminate this blind spot.

The fact that the three closest passes ever observed have all come in the last 18 months isn’t anything to lose sleep over. It doesn’t mean asteroids are swarming Earth; actually, it reflects improvements in sky surveying technology and astronomers’ ability to spot and track more near-Earth objects. If anything, more known asteroids should allow us to rest easier at night.

Instagram Adds New Features, Including Reposts and Maps

Feed posts and public reels can now be reshared on the popular social-networking app.

Instagram has launched new features aimed at further connecting users with their online contacts, the company announced Wednesday. One involves sharing public feed posts and reels, another shares locations with others on an Instagram map, and a new Friends tab shows what content your contacts have liked or commented on.

For reposts, you’ll be able to share public reels and feed posts from other users. The original poster will be credited and those reshares will appear in the sharer’s profile in a new tab. Posts and reels will now include a reshare icon when they’re available to share.

Instagram says creators will be able to reach more people since those posts will be recommended to others’ followers.

You have to enable the new map feature to start sharing your last active location. You can set who can see your location and can also choose not to share your location when you’re in specific places, or have your location available to specific users.

Location sharing can be disabled at any time, Instagram says. Reels, posts and stories can be viewed through the map.

Also, a new Friends tab at the top of Reels shows public content from contacts. This feature has been available previously, but is now being expanded globally.

You can opt out of having your content displayed in the tab with options to hide likes, comments and reposts. You can also mute likes, comments and reposts from accounts you follow.

How to Play Battlefield 6 Beta: Open Access Resumes This Friday

The Battlefield 6 open beta for all will open back up this weekend, starting on Aug. 14.

EA’s DICE studio has blown the lid off the multiplayer for its upcoming military shooter Battlefield 6, and after an exciting first beta weekend, you can join the fray again in just a few days. Battlefield 6’s first public beta is available to everyone and will resume this weekend. It’s not too late to join in, and here’s how.

The Battlefield 6 open beta is the first chance for players to experience the game’s multiplayer before its full release on Oct. 10. While those with early access got a couple extra days to play and the first open beta weekend was a rousing success, if you didn’t get to play, don’t worry — the second weekend will kick off at 1 a.m. PT on Aug. 14 and run through Aug. 16.

Fans can visit Battlefield’s website to get info for the open beta, which just requires linking your EA account to your platform account. PC players will also have to configure their system to Secure Boot as well (see below).

The beta will be playable on PC, PS5, and Xbox Series X and S.

When does the Battlefield 6 beta end? What are the dates and times?

Aug. 7-8: Early access.
Aug. 9-10: First open beta weekend available to all.
Aug. 14-16: Second open beta weekend available to all, starting at 1 a.m. PT on Aug. 14 and closing Aug. 17 at 1 a.m. PT.

How to access the Battlefield 6 open beta

As this is an open beta, getting access is pretty easy. Simply download the Battlefield 6 beta client from your preferred platform, including the PS5, Xbox Series X and S, Steam, Epic Games Store or the EA app.

Preloading the Battlefield 6 beta started on Aug. 4. Doing a preload means you’ll be able to jump on the beta as soon as it’s available instead of waiting for it to download on the day of access.

Battlefield 6 open beta download links

Here are the BF6 Beta download links for each platform:

PC-specific notice for Battlefield 6 beta

A special note if you haven’t played a Battlefield game on PC recently: Studio DICE and EA recently started requiring players to set their computers to Secure Boot when playing Battlefield games to combat cheaters, and Battlefield 6 is no different. To even play the open beta, you’ll need to delve into your BIOS and switch your PC to Secure Boot. Check EA’s guide for help.
